Hello Robin,
Your translation is correct. Also your story about the gates in the town Utrecht.
Jaspar (also written as: Jasper, Casper or Casparus) was indeed married to Catharina Bisgangh on August 30, 1738 in Utrecht.
Jaspar de Groot and Catharina Stammels (also written as Stammen, Stammens, Stammers, Stammer, Stam) have had at least 9 children. Their religion was Roman Catholic.
Jasper de Groot was baptized on September 15, 1714 in Utrecht.
His father was Joannis de Groot and his mother was Cornelia Copier.
Jan (Joannis, Joannes) de Groot and Cornelia Copier married on November 19, 1712 in Utrecht.
Why I’m sure of this:
The first child of Jaspar de Groot and Catharina Stammers was baptized on September 6, 1744 in Utrecht as:
Joannes de Groot, this son was renamed to the father of Jaspar de Groot. (A custom in Holland in that time, to rename the first son to the paternal father).
Cornelia Copier (at this baptism written as Cobier), is the mother of Jaspar de Groot and was a witness at the baptism.
I hope this gives you some more information.
Regards,
Robert A. van Duuren.
