My great grandfather, Salomon Izak, was born in Groningen in 1846 and died in Amsterdam, after two marriages, in 1909.
He is sometimes, mistakenly, called Salomon Bollegraaf or Salomon Izaak Bollegraaf (see my contributions to this forum a year ort two ago.
I know about his line of descent from Isaac Simons Bollegraaf, his marriages and children, but I know little more about him: his work, where he lived, whether he ever had any clashes with the law and so on.
Does anyone know more or have good ideas where to look???
Cheers
Geoff
