I am working on my family tree and my father's mother (my grandmother) was adopted. She did not know this until late in her life when she went to get a passport to travel out of the US. She was born in 1925 or 1926, and the only record I can find of her online is the 1930 census, in which her information is filled out as if her adoptive parents are her true parents. Apparently it was a big "hush-hush" secret that her adoptive parents tried to convince her of her whole life, so she never had any indication of being adopted until late. How can I use genealogical resources to locate her adoption record or birth record or both? My ultimate goal is to find out the names of her birth parents to begin tracing their ancestry. Thank you in advance!
