My great grandmother was Rivka HEIDT (1870-1930?)
She married Faitel Lukin in Belarus (he was >from Minsk)
and came to the States (where he becomes Philip and
she Rebecca) in 1909. I have found her brother Joseph
in the States, so I am sure of the spelling of HEIDT in the US.
I can't find anything about her (or Joseph) in Belarus.
