I am researching my ancestor William Tidball, a son of Thomas and Elizabeth. There is confusion as to who the mother was of William's daughter Mary (born in 1768). Some trees list the mother as William's first wife Miss ? Sheely (1740-1776). They were married in 1764 0r 1765. Other trees list Margaret Buchanan (1755-1792) as the mother of Mary, with a marriage date to William of 1778. Were there 2 wives? Who was Mary's mother?
I appreciate any help someone can give! Shirley
