Thank you for the information. After I posted earlier I did go to Familysearch.org and did locate Mark & Wesley with the information you provided.
I guess my biggest hurdle now is locating Mr. & Mrs. L. B. Olin who lived in Maryland in 1960. I did look in the SSI at familysearch.org and found may L's for Olin, but none for Maryland. I guess they could have moved too. My friend has no information on them nor their given names.
