I'm very glad to be of help to you, Adrienne. If you need more, just let me know (egelling at shaw dot ca).
Thank you for the information on Elizabeth Lace, which I didn't have. I've been able to trace her son Thomas Corkill down to the 1911 census with a very large family, though I couldn't find him as a 2yo in 1861. His marriage in 1886 on the IGI identifies his father as "John Corkill".
One question regarding Elizabeth's death. In the first note you said it was 1867 and there is a Marown burial on Brian's list for an Elizabeth Lace age 33 for 6 July 1867. However, in your second note the gravestone is 4 July 1869 aged 30 years. She was baptized 1 Jan 1837 Marown, so she would be 30 in July 1867 and 32 in July 1869. Which one do I pick?
