Looking for my Dutch ancestors who came to Holland from Germany before 1700 surname Berlin(er) Berlijn

I do not know the Dutch computer terms ,so please correct my mistakes.
I am looking to find out where our family originated,most likely Germany.or Poland.
The earliest data I have is 1720 of David Jacob Berlijn(Berliner) born 1720 Amsterdam married to
Rebecca Levie born1721 in Amsterdam. Is there anyone who could find anything from Germany, as I don't
speak the language......Where do I start.
Thank's anyone who will reply .
