Thanks for that - I'm having trouble working this one out - does that mean your grandparents were John George Shaw Phillips (1888) and Alice Ashton (1886)? I have no note of any of their children except possibly a Florence in 1925? Your other grandparents were William Cleland Phillips and Emma Holt?
Just to keep you up-to-date with what I have discovered:
As you would have worked out from reading the previous posts, your grandfather's grandparents were William Phillips and Alicia Clawson.
I have made some headaway over the last few years on the siblings of William Phillips. Eldest was Martha Ann (1829, my ancestor) then your William (1830). After that I think there were another 9 children: John (about 1832), Elizabeth (1834), Samuel Cleland (1835), Mary Jane (1838), James (possibly 1840, not yet confirmed), Helen (1843, may have died when a child as I can find no trace of her after 1851), Sarah (1847), Ellen Margaret (1848), Andrew Thomas Clarke (1849). Andrew's baptism confirmed he was the 11th child in the family so I think I have now traced them all.
I am aware of at least 44 children that were born to these 11 siblings (there were probably more) so as you can see there are probably a lot of people out there that have descended from this one family.
Hope that information is of interest.
