Found them!

After my last post, I decided to google "St. John's Orthodox Church Cemetary Perth Amboy NJ" and guess what I found?






YES!!!!!!!!

So now we know:
Alexander died in 1935 and Irene died in 1942. Their birth years are both 3 years off from my records. (Irene 1869 and Alex 1859). It seems like the engraver put a 6 where there should be a 9. In any case, this does still show them 10 years apart.
