This woman was given supplemental baptism at the age of 27, as was her younger sister (in 1842). Both marry here, the marriages being in Protestant churches prior to this baptism. The marriages name no parents, but these baptisms do (as well as the names of their spouses so there can be no mistake).
There are 2 locations given on them ''Île Donay'' and ''Cherbourg''. Anybody have a clue where either one would be? Cherbourg appears to be the one I have linked from Wikipedia in notes, Île Donay is more of a mystery, the closest I can find is Donnay, which is in Calvados, and not an island.
Any help would be appreciated to figure this woman out, grandmother to the first woman doctor in this province (who founded 2 of the biggest children's hospitals)
