Hello,
We don't usually include family trees in our McCobb book unless they have at least 3 generations of the McCobb surname. Your James McCobb line did have 3 McCobb males, but all remained single. However, when I found the Australian connection and that the Heylen line has present day descendants, as does your Semple line, we decided to add James as our Ancestor 23. Since our database is already 5500 names and the surname directory is already 30 pages, we only carry the maternal lines down 2 generations. If we tried to add all of the Semple descendants, it would be too much. It looks like the mccoywest public tree in Ancestry is fairly complete, so we will use it.
In my very extensive research, I have looked at every census page for any McCobb, including variant spellings. I probly spent 15 hours just trying to connect Jane, Martha, and Isabella in Australia. I hit the jackpot when looking at their immigration documents. Jane was the first one there and she served as the sponsor for Martha, Margaret, and Isabella. On Apr 10, 1862, Jane made deposits for Margaret, age 18 and Martha, age 20. Martha arrived in Aust on Jan 18, 1863. On her manifest, it said she was from Raymoghy and that her parents were James and Nancy McCobb and that Jane was her sister. On May 19, 1863, Margaret applied for a deposit refund (Jane finally got it in 1868), because she never did embark. But, then on Nov 19, 1863, Margaret (once again), age 19, and Isabella, only 14 had deposits made by Jane for their immigration. On Dec 5, 1863, Martha arrived in Australia. On Jan 28, 1864, Isabella arrived and her home was shown as Manorcunningham and she was sponsored by sisters Martha and Jane. Ultimately, it appears that Margaret never did join her sisters in Australia. These records are on Ancestry.com
Feel free to share this info with Susan and Mark or whoever.
