Sorry for the delay in getting back to you. My son was born 2 weeks before you sent the message and things have been a bit busy since then!! What information are you looking for, specifically? The furthest back I go for Pijart is to Adam, born in 1570 in the neighborhood of St-Benoît, in Paris. For the Bolduc/Boulduc side, I've gotten back as far as an Henri Boulduc, born in 1489 in the city of Senlis, France (Oise department, region of Picardie). Let me know if you want to know about anyone's professions or anything else!
All the Best,
