Your information is interesting, but Marie Ritter is said to be from/born in Alsace. She married her first husband, Jean Baptiste David, an Acadian, in Maryland and is supposed to have traveled with him to Opelousas, Louisiana by 1777. They had a son, Jean Baptiste David II then David I died and she married second my ancestor Jacque Deroziers with whom she had a son, Francois Deroziers, in 1778. When Jacque died she married third Jacob Bihm (who was from Pennsylvania) and had I think five more children.
Could you share the source(s) for your information? I think the 1749 birth date is pretty accurate according to the age given for her when she died in 1809.
