Hello Malodie,
Triggered by the "Jehansdotter" above, I looked at the profiles on Geni, You'll see that a Scandinavian has entered the data, probably using some Scandinavian genealogy site - because there would be no such thing as "Jehansdotter" in France (but it is obviously the Scandinavian way of saying "daughter of Jean"). So, they are not reliable names to search for anywhere else.
Where are these "de la Montagne" supposed to be from? Do you suspect they relate to de la Montagne in New Netherland? You're mentioning the UK, and given the timeframe these might be related to French refugees that came through Leiden (NL) to the UK but also to New Amsterdam.
Please give some more clues as to the family context? If the above may be correct, I can dig into the original Leiden records.

Hi George! Sure i will give you as much info as i know. Give me a week to work on it for you

Best regards and thanks,
Malodie
