Your grandfather would be my 2nd cousin once removed.My grandfather's mother was Erzsebet Horvath b. 5 May 1853 in Doroslov, Hungary.Erzsebet was the sister of Janos Horvath, the father of your greatgrandfather Andrew.
Magdalena Reich/Reichman was the godmother of my Aunt Julia.
I have info on our Horvath line back to Janos b. c. 1800 who married Erzsebet Gombas.I would be glad to share info !!I've been sorting the 3 separate Horvath clans of Barberton for years.
Please email me directly, I think it would be a lot easier.
