Kara,
I did a search for the Chesapeake Beach area and the Street Address you wrote. The only Frank Bristow that shows up is the following:
Frank J Jr Bristow
142 Clyde Ave
Lansdowne, MD 21227
(410) 247-0204
Not sure if this is who you are looking for, I found this information at Superpages.com under People Search.
Good Luck. I am in the process of trying to find any information on my daughter that is now 22.
