It's me once more. If your "Nattie" married a (first name UNK) Gregson and they lived in Elk Mills, MD we have the same connection.
Her name was Nathiss Bullock and was born Dec, 1884. She was my grandmothers sister. Her nick name as a child was Nat. In the 1900 census she worked as a house keeper.
If this is the connection please contact me. I do have info on their other siblings if you desire to have it.
