I am looking for the date my G. Grandmother died.

Name: Margaret Perron Strandberg
Died in: Ludington MI
Buried in Ludington
Children: Frederick, Bob, Margaret, Pauline, Carl
Parents: Teresa (spelling may vary) and George Perron (also saw spelled Perria, Perrie, Perren).

I do know she died after 1954 because my mother does recall knowing/meeting her.
