Maurice De Jongh Amsterdam 1774 - Lautenbach, Alsace 1853, cotton spinner and merchant in Manchester, Liverpool, London and Warrington.
During the years in England he had three business partners with the name De Jongh: Joseph b abt 1774 Oostende, John b abt 1885 Oostende, and James abt 1890.
Very likely they were brothers, and to prove it I need to find their parents through some kind of birth record.
No result in Amsterdam for a Maurice or a Dutch variant of the name.The closest I got was a Jewish circumcision in 1774, a Mordechaj, no surname, no parents.

So I would like to find the others in Oostende. There may have been a sister Harriet Eliza too, b abt 1783.
Possibly their names were anglicized, and originally Dutch, maybe Jewish.

Of Joseph and John there are records of adult baptisms in Liverpool (CoE). A reason why we believe they may have been Jewish. But not sure of it.

So, how do I go about it? No De Jonghs from Oostende in the Brussels State Archives database, but I understand from another thread it isn't complete?

And where could I find information about Jewish records of that time (births and circumcisions)?
I understand there wasn't a real Jewish community in Oostende, so they may have gotten a rabbi elsewhere.

I read something about an Ezechiel De Jongh from Amsterdam, a textile broker, who was (one of) the first who applied for and got citizens rights in Oostende. That was in 1781. Would people need to apply before or as soon as they got somewhere? Or could they have been living and doing their business there for 5 or 6 years?

Any tips, addresses, internet fora etc etc are welcome.
