Ste. Marguerite d'Youville and her husband had five children before he died in 1730 and she was two months pregnant with the sixth child at the time of his death, so this child was born seven months after the father had died.
I have the PRDH family record, but have not yet looked up the actual baptism records. Four of the children died as infants. I do not see any records that the other two married.
