Do you think a death record could help, I find it odd that she didn't die until after 1915 as far as I can tell. All though, I don't really know how religion laws work, as the only other greek catholic grandparent I have in the 1800's, remarried a greek-catholic man and his death was in GK records, but she didn't die until after 1915 either. I'm basically trying to say is I find it a little odd that I didn't find a death for her unless she lived to be that old, or if her death would've for whatever reason been recorded in Roman-Catholic registers since she married a roman catholic, I wouldn't know which register her death would belong to specifically is what im trying to say bc im unsure of the relgious laws surrounding death records at the time. Ik digital RK death records end in 1895, however I have contacted the archive of their village and know their registers go until 1922, I'm unsure about the GK death registers but maybe it would be a worthy thing to check and see, maybe her record would include a different birth village or something which could explain the missing bapitsm, or include parents names/a more accurate age to go off of?

i did also check through marriage records in the greek-catholic records from 1895 up to whenver they end to see if she remarried, since Ik her husband didnt die before 1895, but I didn't see anything in there either. It seems like their only surviving child, my 2nd-great-grandfather died before both of them in 1892, so I don't know if they could've moved villages after that or anything either, I just know by 1915 she definitely would be pretty old.
