I am at the early stages, but so far have discovered that my Great grandfather was William Lilly McColl b: 27/08/1884 (married Geraldine Park on 23/9/1910) William's father was Robert McColl b. abt. 1852 East Kilbride, Lanark, Scotland, and mother Martha Lilly b. February 1860. William was one of 6 children in 1901: Jeanie, Barbara; Martha L; Robert and Alexander. Janet and Archibald do not show on the 1901 Census but they would have been in their 20's, so that is not surprising.
In summary: William & Geraldine had atleast one son: Thomas McColl who married my Grandmother Margaret Sexton of Coatbridge. They married in Glasgow in the Church of Scotland although she was a Roman Catholic. They had 3 children = all are still alive today. I am teh eldest daughter of the youngest son: Valerie Harper (nee McColl)
If you want me to send you a copy of the finished tree, I am quite happy to do that but it won't be in the short term as I am still investigating it.
I look forward to hearing from you and would sincerely appreciate any information on Martha Lilly's parents / grandparents as that would save me a bucket of time and money.
