Hi Jean.
I am sory, I mistificed you in my reply. I opened the register of Kolovec and verified family Neuheupl there. There is noticed in the index - Kolovec - book # 15 picture 77 over that Neuhaupl was also recorded as Leihaupl.
I found MARGARETHA NAJHAJPLIN 18 years old (born 1767) who married in May 1785 to Adam Baucz widower 40 years old. (Kolovec 7, picture 1).
This Margaretha is really this one you found. I confronted first letter of Martin's surname to another name in next page in 3rd record (from 5th Sep.). There is the same letter used in name Norbertus.( Kolovec # 2, picture 392)
According to this we need to read Martin's surname as NEJHEYPL !!!

It exist all 3 modification of this surname in Bohemia - Neuhaupl, Lainhaupl and Langheupl.

I am sory ones again.
Tony.
