Alonzo PULVER probably born June 1865 in New York married a Sylvia DUNAGAN (1865- abt 1940). She was from the Catskill Mountains area of New York (Ulster or Sullivan County) thus Alonzo may have been from that area as well. In the 1900 census they are in Rosendale, Ulster County, NY
The family included the following children:
Minnie:b. 1881 Benjamin: b. 1886 Gracie: b. 1888 Henry: b. 1890 Arthur: b. 1892 Frank: b. 1895 William: b. 1896
In the 1920 census, Sylvia was a widow living in Cambridge, Mass with son Benjamin.There were no Pulvers in Rosendale in 1920, thus I am not sure where the rest of them went.A search of the Mass and New York Soundex in 1920 gave few clues that these children (now adults) were in those states.
