William Weisz born 1900 in Komarno, Slovakia presents a great example of how Jews from Austria-Hungary often have their names spelled differently in every document.

I'd be curious to see what name is used on William's birth record, which should be at the FHL, International B1 Floor Film 2254224 Item 1 No 5363614
https://www.familysearch.org/search/catalog/1057198?availability=Fa...
not all "Sams" are Shmuel. An Ashhkenazi Jewish man would not give his son the same name as his. So ,if the family is Jewish, it shows one of the reasons for knowing a person's Yiddish/Hebrew name, & helps to avoid confusion. In my family's case we found sam, my greatgrandfather was Shmuel and always cled Shmuel not Sam & his son Sam,my great uncle was Shmerel.
The FHL 2254224 / DGS 5363614 is for Stara Dala / Ogyalla. If William was born in Komarno, then it wouldn't be there.
Available Jewish records for Komarno ar at FHL 2287072 / DGS 5363621, but the newest record is from 1895.
So 1900 births are in Komarno Civil records only - Komarno archive, physical book, not digitized.
