Dollie......it sounds as if my grandmother, Elizabeth Agnes
Sprenger Mattoon, might have been his sister. She was born May 29, 1890 ....Westchester, Cty. Perhaps Yonkers/Pawling or Phelem. She was the daughter of
Catherin Curtin ( Burtin was found in one source) and John
Sprenger. I do remember visiting cousins in Mamaronack,NY area and in Mt Vernon, NY. I have contacted several living cousins to try to piece stuff together. Hopefully, someone will have some records.
