Thank you for the information. This is definitely the family that I need information on. I am working on a Hamilton tree and have a picture with Alexander (and of course the father was too old for the date of the picture), and Grace Percival Blackburn included with others at a Hamilton gathering. I had no way of placing them. Is it possible to get the rest of the information on their descendants ? My e-mail address is email@example.comI would really appreciate it. Thanks again.
