Hello,
I am not sure if we are related maybe not, but if your
grandfather came from the village of Zywaczir, in the
Tloematskij rayon, Province of Ivano Frankiwska, Western Ukraine, we could be related, although the name ILczyszyn
is very random, it comes from the first name ILKO, just as info.
I myself live in the U.K.-England., but do not have many family left anymore, with the name ILczyszyn.
Kind Regards,
Andrij
