I think we are your ancestors from České budějovice in Czech republic.
Jan Lapice from Novosedly near Třeboň was my great great great grandfather and I'm the last in the "family line" from his son Jakub Lapice, who was born in 1843.
It's amazing that I've found your message today,because three before we were at Lapice to find foundations of Lapice citadel, which was the boundary citadel between the domains of Jindříchův Hradec and Třeboň and was built near present junction of the rivers Nežárka nad Nová řeka.
We are trying to find the nation of our ancestor Lapice, because it is very unusual surname in Czech republic. We think he could be from Spain or Italy because we know that his name was changed to Lapice from something like De Lapice.
We are in contact with the Lapica, who you found in the phone book and we also have some birth and marriage certificates, which you may be intrested in.
So, if you want to contact me, please write me on email@example.com
I'm looking forward to your answer.
