Dorothy,
I am amazed at all the William Moores there were in IOM - sort of like John Smith. Yes I also have many dates for my great grandfathers birth date. 1832-1839 I do not know his siblings names but I may know his parents name soon. (Probably William Moore) :)He came to Oswego,New York thru Canada in 1964 (from 1900)census. If you are interested I have all his children's names and have been to his cemetery plot in Oswego. Perhaps this is the same man - that would be amazing - so if you can think of anything elso to match just ask.
Thanks for responding,
Flo
