Requesting information on Kastelic families. My daughter is a Kastelic by birth and has a birth certificate that indicates her great grandfather was a Joe Kastelic and that he was born in Austria and immigrated to the U.S. near the turn of the century. Family rumor is that the original name could have been Kastelch or something similar. Any help you could give us would be greatly appreciated. Her grandfather would have been John William Kastelic and would have lived in Michigan or Illinois. He was killed in a car accident in the 1950's.
