[Macedonian Croatian > English] Photos of graves

Hey everyone, I’ve just found some old photos and I believe they’re of my great-grandparents and great-great-grandparents graves. The writing is in Macedonian and Croatian I believe and I’d like some help translating what is written on the graves and how to spell the names in English please! Also, if anyone has any tips on any websites or ways to research Eastern European genealogy I would greatly appreciate it! My grandparents and great-grandparents were from small villages so it’s quite difficult to find records of them, this is the furthest I’ve managed to get. Photos posted below
Thank you :)
