Glassport, Allegheny County, PA.:

Glassport has an approximate population of 5,582 people. Glassport was named after the Pittsburgh Glass Company. It is located near the Monongahela River on Seventh Street. They specialized in "pressed glass," tableware, and other glass products made from molds. The Glassport factory took $68,497.00 to build in the mid-1890's. Passenger trains brought workers to town. It was one of the largest handcraft glass manufacturing facilities in America before pressed glass became inexpensive. They produced 15,000 different items of ordinary staple glassware.

(My father worked in a glass factory in his youth)

Glassport, PA. seceded from Port Vue in 1902. On August 3, 1963, the glass plant was damaged by a tornado, and their 80-foot water tower collapsed through the building's roof. When the high winds did this, all the furnaces shut down and the liquid glass cooled and hardened. Afterwards there was left a 250 ton block of solid glass. After the tornado, there were plans to re-open, after repairs, but this day never came because of the high price of re-building. During the Depression, Glassport's plant was the only one still running, while many other plants were closed due to hard times.

The Good Luck Coal Mine was owned by the United States Glass Company and was located in Glassport from circa 1919.

(where all the men in the Sypniewski family worked here from time to time).

The August 3, 1963, the tornado also damaged the Petrosky Hotel, and two people died there. Glassport lost a lot of money in the aftermath of this storm, and there was much re-construction to be done.

This information is from the writings of Mr. Richard A. Uher.

Glassport Churches:

An earlier event that changed Glassport was a fire involving the Holy Cross Polish Catholic Church located on Seventh and Delaware Avenue. The damage was estimated at between $25-30,000.00. A frame building owned by Joseph Moslosky was also burned on that morning (1:15 a.m.) Father Albert Jastrzyinski, their pastor, was in North Carolina at the time of the fire. (McKeesport Daily News - January 22, 1907).

The temporary church was located in the Dietrick building next door to the Foreign Exchange Bank on Monongahela Avenue. Rev. Father A. Garstka, formerly of Glassport, raised funds to built the Holy Cross Church. It was thought that the fire was the result of a defective flue. However, others felt there was foul play.

This information is from the writings of Mr. Richard A. Uher.

St. Cecilia was the Sypniewski family's church of choice after Holy Cross burned. Father Walter A. O'Hara was the third pastor of St. Cecilia. He was born September 26, 1884 in Ebensburg, Pennsylvania. He was the son of John A. O'Hara and Anna R. Rosensteel. He was the second born of four children. Walter was ordained at Mount St. Mary College and Seminary in Emmitburg, Maryland. He had a Masters of Arts Degree from St. Mary's Bachelor of Canon Law degree and a Licentiate in Sacred Theology from Catholic University Assistant. He was pastor of St. Cecilia, in Glassport from 1926-1971. He would have celebrated his 68th anniversary as a priest on June 1976.

This information is from the writings of Mr. Richard A. Uher.

Another Glassport Polish Church is the present Queen of the Rosary Parish on 530 Michigan Avenue in Glassport, Pennsylvania, that houses the records of the earlier churches of Glassport.

McKeesport Hospital:

Old McKeesport Hospital - where most Glassport residents were born. The hospital opened in 1891.

R.L. Polk's Directories for Glassport:

The first Sypniewski to be listed in R.L. Polk's 1920 Glassport Directory is Kazmierz Sypniewski ("Kasmer Sypinaski" was a misspelling) as a miner. He most likely worked at the Good Luck Mine which opened circa 1919. Kasimierz lived at 642 Delaware Street, in 1920. In the 1930's directory there is a "Chas. Sipnefski" (should be Kazimierz Sypniewski). Kazimierz was a millright and lived at 549 Pacific Avenue, in 1930.

This information is from the writings of Mr. Richard A. Uher.

***These facts are confirmed on his marriage license and death certificate. Kazimierz would live at 549 Pacific Avenue for most of his married life. They lived in an old commercial building and owned property nearby, which they later gave to their children.

The Family of Kazimierz Sypniewski, my grandfather:

1910 Census: Pittsburgh,taken May 3, 1910, Allegheny County, PA.: On Pennsylvania Avenue

  • Frank Modjeski - head - age 29 - born in Germany - 1884 - speaks English - Car Inspector for the Railroad
  • Eugenia Modjeska - wife - age 26 - born in Russia/Lithuanian - 1887 - speaks English
  • Gertrude Modjeska - daughter - age 6 - born in Pennsylvania - speaks English
  • Albert Modjeski - son - age 3 - born in Pennsylvania - speaks English
  • Florence Modjeska - daughter - age 7 months - born in Pennsylvania
  • Casimir W. Sypniewski - boarder - age 35 - born in Russia/Poland - 1875 - Parents born in Russia/Poland - Speaks English - Attorney-at-law
  • Felicia Armalona - mother-in-law - age 50 - 1887

Casimir W. Sypniewski is also listed in the Ellis Island Records.

I also found a graphic portrait of C.W. Sypniewski - lawyer at:

Historic Pittsburgh Click on p. 183 for the portrait.

I do not think this is my grandfather, but possibly is a relative of his? My father said that one relative came to the U.S.A. and returned to Poland when he could not find work in his area of expertise. If this Casimir had remained, he would have been age 45 in the next (1920) census.

What is interesting is that they both Kasimierz/Casimir were connected to a family called Modjeska/Modzelewska of Pittsburgh, Pennsylvania. One roomed with them and one married Veronica (Weronika in Polish) Modzielewska. Family stories revolved around the fact that the actress Modjeska was related to this family. If you explore this you see that a Sypniewski was a friend of the famous Polish Actress.

***The name is spelled "Sypniewski" on ALL other civil records

Kazimierz Sypniewski was born, in Poland, on March 8, 1884, but fled during an uprising, to escape the Russians. He worked for a time on the Brandenburg (registered in Bremen, Germany). When he got enough money saved he jumped ship, and eventually settled in Glassport, Pennsylvania.

Weronika [Polish form of Veronica]Modzelewska was born in Lomza Province, Poland; on January 5, 1889. She was the daughter of John Modzewlewski and Ewa Gasiewska of Pittsburgh, PA. The Modzewlewski family lived at 104 Pike Street in Pittsburgh, PA. in 1913. They were from the Commonwealth of Poland, diocese Lomeynska. Modzielewski is the original spelling of this name. Weronica married Kazimierz Sypniewski on July 2, 1913, in Glassport, Allegheny County, Pennsylvania. They settled in Glassport for all their lives, and Kazmierz first worked as a mill worker and later coal mining again. This job choice cost him an early grave as he acquired black lung disease. Kazimierz died March 10, 1947, of pulmonary tuberculosis (death certificate) at 549 Pacific Avenue. Veronica died May 28, 1968 at McKeesport Hospital. Both Kazimierz and Veronica are buried in St. Mary's Polish Cemetary.

Child 2:

.....Bojemond Sypniewski was age 5 in 1920 census (b. 1915). He would have been 15 in the 1930 census, but he is not listed, so he may have died young?

The Schmotzer Family was one of the earliest citizens of Glassport, PA. In R. L. Polk's & Company's 1897-1898 directory (when it was still part of Port Vue), a Frank F. Schmotzer is listed as a grocer, and railroad employee. In the 1910 Polk's, there is a John Schmotzer listed as a laborer living at 601 Indiana Ave. in Glassport.
