The information about Maureen S. Foster's death is available on Ancestry.com. Her SS# is listed so it would be easy to cross reference to the SSDI. She does appear in the SSDI, so it would be easy to write for a copy of her original SS application if the information on it will help you. Her husband's name was Marion P. Foster born 10/13/1931 in Ohio.He died in 1997. I can try to contact the person who submitted this Family Tree information to ANcestry.com but he hasn't been active since 2003.
Maureen was apparently married previously to someone named Jammer who lived in Ireland.
