The obit shows her maiden name was "Green". The 1920 census shows "Annie M." was born in Connecticut, the 1910 and 1930 census also shows she was born CT. In the 1910 census it looks like she is single, works in a silver shop and rooming with the Joseph Lynch family in Wallingford, CT.
The census information points to a marriage year of about 1915. There is a good chance that his parents would be named in that marriage record.
