Ronald means 'powerful, mighty' and the closest thing I can come with Weasley is 'weasel' xx;;

Means "Running Weasel" in another language. It was also a stratigist who was brilliant at chess and never lost a game. (like Ron!) Now listen to this! "Running Weasel" died one day when a rat had been dyed yellow by his soldiers for fun, and he knocked over a lamp in his palace, which burned to the ground-killing him!

Ronald
"As Ronald you have a great love of nature and the out-of-doors, and could have a desire to be in an occupation which takes you outdoors and involves you with the products of the earth. All the finer things of life and beauties of nature are an inspiration to you and you are attracted to the mysteries of nature. Difficulty in expression results in your being too positive, blunt, and candid in speech. Although you are easily offended by others, you do not show it. You crave affection and understanding, but rarely find it as others do not understand you and accuse you of being cool and aloof. The average person would never realize the true depth of your nature. A very individual, independent person, you live within your own thoughts. The insecurity you experience from limited verbal expression and social ease results in a jealous possessiveness and suffering through frustration, repressed emotion, and self-consciousness. This name would cause tension affecting the eyes, teeth, sinuses, ears or throat troubles; there could also be sensitivity in the heart, lungs, and respiratory organs, and frequent headaches."

Ron
"The name of Ron has made you serious-minded, responsible, and stable. You love the security of a home and family, you are fond of children, and, as a parent you would be fair and understanding. Although you have good business judgment, you are not aggressive in your dealings because you do not like to create issues. You would be successful in any position dealing with the public as you have a diplomatic and tactful manner and possess a charming, easy-going nature which puts people at ease. People are drawn to you because they feel that you are patient, kind, understanding, and responsive. You would be effective in a career or in volunteer work where you are handling people and serving in a humanitarian way. While you are honest and responsible, one weakness that is paramount in your life is your lack of self-confidence and initiative, which causes you to put things off and avoid facing issues. Generally speaking, you have few problems with your health; however, there is a weakness affecting the fluid functions of the body."

Weasley
"Your last name of Weasley creates individuality, independence, self-confidence, initiative, and an inclination to physical activity. You are not inclined to merge your opinions and viewpoints with others, to accept compromise, or to work in a subservient position against your will. Your expression is invariably quite direct and candid, and lacks the moderating tone of tact, diplomacy, and friendliness. Others find it difficult to accept your domineering and, at times, argumentative manner. Your circle of friends is restricted to those of like nature. Once friendship is established, you are very loyal and steadfast and do not tolerate gossip or criticism. In your close associations and family life, there is little demonstration of sentiment, appreciation, sympathy, or encouragement. It is difficult for you to find the right words for such circumstances. Weaknesses in the health caused by this name centre in the head."
