I looked through the Barssel Catholic birth/baptism records
and couldn't find anyone who fits Angela born around 1740.
The only instance of a variation of this surname I found in the years around
1740 was a Catharina Hülpers, born August 23, 1737 in Barssel,
the daughter
of Bernardus Hülpers and Margaretha Drirbon? (the mother's surname
was very hard to read). These might also be Angela's parents.
I also found the surname Hülpers many years later in Barssel records.
