I just today received my mother's birth certificate that I applied for with the Maryland Archives. I had to fill out an application and send $25.
She was born in 1917 and died last month.
I have been doing research on my family and was able to track down her mother (my grandmother) and relatives to when they immigrated from Germany. Well, it appears my mother was adopted from St. Vincent's Infant Asylum because that name was on the birth certificate as place of birth. The mother and father were unknown altho the age for the mother was 24.
You can get certified birth certificates from the Maryland Archives if the person was born before 1924 and you fill out an application.
Maybe your grandfather's birth certificate will have the mother and/or father listed.
BTW here is the link to St. Vincent's: http://www.catholiccharities-md.org/st-vincents-center/histo...
