Hi, my name is Mark, I am from Vilnius, Lithuania. Looking for the last name Kasperowicz, I I've across your message. I am not 100% positive, but I think the right way to spell the last name of your greatgranfather would be KaspAr... (with an "A", otherwise it is difficult to pronounce). Once again, I am not sure, but I think that that would be the right way to spell. If you have any questions you are welcome to write to my email adress (I don't browse through the internet very often).
