Finally got around to making a couple more charts.

1.) The MAHONEY chart is extracted from Paul's work.
Hadn't noticed before, but chart shows that of the 6 children, 3 died in 1913-14. Must have been a local epidemic of some sort.

2.) COYLE/WILLIER chart is an extract from the voluminous COYLE chart.

3.) In browsing the web over a few years, it's quite noticeable that there is a constant addition of new material.
Happened across the source of the 'Thomas Willier' biography. Searched for 'Willier Construction Co.' and got a surprise when another name popped up, 'James Harrison Hedges'. See 'Willier Construction Co.' The reference is near the end of his write-up.
