A few months ago, I asked for some help concerning
a Mordecai COHEN of Amsterdam who could have been a descendant
of Rabbi David COHEN-HANAU of Altona-Hamburg.
I have got some interesting answers and tried to do a connection,
but as I said then, it was not sure at all.
My Mordecai COHEN (1659-1723, Amsterdam) married there in
1679 with Duijfe Taub Mozes Joseph (1659-1736, Amsterdam).
He was a son of Isaac COHEN. I don't know more.
