Thanks Gwyn.........unfortunately not enough is known on the family to have a clue as to what to look for and where. No siblings, no census info, no death info :) James Williamson (son of Jean Sillars mentioned in my previous post) and his wife, Anne CALDER, had 9 children and I get a feeling that the forenames of two of their children, David and Andrew, are from the Williamson branch of the tree. With the naming of James and Anne's first son, James in 1843....took care of naming after both grandparents and the father (James Williamson, James CALDER and James Williamson, respectively). The second son was William and I have a feeling that he was named in honor of Anne Calder's brother William. William was born in 1814 Nairn, came over to North Dumfries, Waterloo, Ontario with some of the family in 1832 and tragically died at the tender age of 19 from Cholera (an epidemic that swept through Galt (Cambridge, Ontario) in the summer of 1834). The third son was named David (my direct line) and then Andrew followed. Although I realize that naming patterns were not cast in stone, James Williamson and Anne Calder seemed to follow it as well as Anne's siblings. To make things more complicated, I have run into the same problem with James CALDER (Anne Calder's father) b. 1785 Nairn. His was the only registered / surviving christening to his parents. So in a nutshell, I do not know enough about either side (Williamson / CALDER) to even attempt to go looking for those related as I would not be able to "prove" them. James Calder did have a sister Isabella b. abt. 1790 but she never married....shows up in census returns living with the James Williamson / Anne Calder family. I have "proved" her as a sister as she is mentioned in James Calder's 1869 Will as "sister" and she herself had a Will...leaving everything to her niece Isabella Williamson. I am certain that Jean Sillars / Sallers / Sellers remained in Scotland as she was quite up in years at the time the photo was taken (mid 1860's). Two different branches of my family hired professional researchers in Scotland in an attempt to "crack the Williamson / Sillars code" but nothing. Many thanks for the encouragement!! Sherry Just one thought that may help - I once puzzled for months over a 'missing' family then a light clicked on in my mind and I found them in the US census return for 1910! They had emigrated in the 1880s and other family members followed in the 1890s. So it is worth considering whether your ancestors went to anywhere 'unexpected'. I say that because although we sometimes think we know where they finished their lives there are often unexplained 'gaps' when sometimes individuals spent 10 years or so in another country and then returned or travelled elsewhere.
