Roline Poëte migrated to New France with her children, possibly at the same time or later than her husband. She is well documented as far as possible.
She is however sitting with ''unknown'' parents and 3 siblings that have no sources. Have dug up a source which names these purported siblings, but there is no relationship established from this source. Basically people being godparents at children's baptisms. Full citation can be found in research notes on Roline's profile.
Can my friends in France take a look and see if they know of further sources? All 3 supposed siblings have basically no data on them. (must read French)
