Maureen- lots of questions to see if we can get any clues to find a location in Ireland.
1. Did Thomas and Anna marry in New York or Ireland and do you know the date?
2. Do you have the marriage certificate? N.Y, certificates ask for lots of details like names of parents, etc.
3. Do you have Anna's death certificate? N.Y, death certificates also have loads of details.
4. Have you found the two brothers, John and Thomas, in 1900 U.S. census? that asks for month and year of birth as well as how long in U.S.
5. Have you asked other Clarke relatives if they have ever heard of a place in Ireland? even the county would be a start.
6. Have you found Anna Clarke arriving in U.S. (Ellis Island probably)? should list port of departure.
