Genealogy / DOLOVITZ - LAST NAME; NEVER SEEN IN AMERICA [11]

I am not sure if this will help you but my grandfather's name was Jacob Dolovitz.
He was born in Rajgrod, Poland about 1873 and came to the UK at the turn of the century - he was a cabinet maker. His wife's name (my grandmother) was Fega Rifka Cohen.

I was once told that we do have Dolovitz/ Dolowitz relatives in the USA but I have never been able to locate them.
