I have some information. John F. Abbott and Adelia Adams had three daughters: Nellie, b. 1889, Md. (the John F. Abbotts were primarily from NJ ending in CA and OR - this Maryland temp.), Marion, b. 1897, and Millicent, b. 1899.
Only Millicent married as far as I can see and the only info I have -m. Cedric D. Sthelen b. 1898. In the 1930 census, they had one son Roger - Pasadena, CA. b. 1928.
I would like very much to contact Roger's family, if anyone knows of Roger Sthelen, please let me know - he is the only known relative of that family that I know of, but he may have later brothers and sisters.
and thanks to Unknown for the family information. Thank you
