Although it was great-grandpa's fond wish to have a more rural life (by farming in the Midwest rather than living in the concrete canyons of New York City), great-grandma Lena Kunstler Farkas (1865-1938) knew she had daughters to marry off. She insisted they live near a ready pool of suitable suitors in the big city. So they stayed put in NYC, moving from Manhattan to the Bronx, which was then a suburban-type area.
Great-grandpa took the oath of US citizenship on June 21, 1906 and his naturalization was filed on June 22, 1906. His witness was Sam Weiss, a real estate dealer. The Weiss name is intertwined with the Farkas and Schwartz families of my mother's family tree, as well as with the names of other cousins like Weiman and Roth, but whether Sam was a relative or an in-law or a colleague, I don't yet know.
