Bacot Family

I have been trying to find out more about the family of Josine Hulscher, who married Francois Bacot, & had a daughter Marie Anne Bacot, who married Pierre Labuscaigne..Now South African trees I have seen here, & elsewhere, give a marriage date of circa !704, in Leewarden, Netherlands..However, according to the Dutch records, a Josina Hulscher, married a Francois Bacot in 1675..I have two dates, one in a church, Hervormde Kerk, in Groningen, on 27th of January; & another in the Burgerlijke Admininistrie, Leewarden on the 6th of February..Would that be a religious ceremony followed by a later Civil Ceremony?..I have found quite a bit of information on Dutch sites about Josina & Francois, & included in Dutch biographies...But, the only child listed of this union is a Gerard Bacot, of which there is quite a lot of information, as he was a successful person in Holland...Now where does Marie Anne Bacot fit in??....I noticed that on the dates for Pierre Bacot, & Jehanne Moreau's children are two Francois..One born in 1644, & One in 1656....however, it seems to be a strange coincidence that each Francois marries a Hulscher girl..One called Josine, & the other Josina!...Possible I suppose, since there are two Francois Bacots!!.....I would like to clear up this discrepancy, as too many times, with South African trees, we are finding errors....Would anyone who has this ancestry be willing to help me with this...Or put me straight, if needs be!...
