sweeny

My grandfather was born in the early 1920's in Louisiana has a adoptee sister named IvaBell whom died svereal years ago. After her death he gave up the search for their birth parents. Birth last name could possibly be sweeny, sweeney from louisiana. Grandfather still alive but no longer able to continue his search. My father would love to find his birth grandparents for sentimental reasons. We are sure the birth paretns have passed away due to the date of birth of my grandfather. But would like to find living family and passed family, especially birth parents.
