I am researching my Chalmers family beginning , I believe, in Girvan in Ayrshire, Scotland. David Chalmers b 1704 married Sara Broun b. 1700 in abt 1720. One child, my ancestor was Ronald Chalmers b 1726 and d 1790. He married Margaret McClymont, their child was John who married Agnes Guthrie. I understand the family originated in Girvan however I dont have an address. the children of John and Agnes were all born in/registered Girvan. I would love to find out what they did and where they lived
