Rory's part of the tombstone didn't change from the beginning of the episode to the end. Thus, he had always died in 1938 and eliminating the Angel Farm didn't change that. If he was 82 in 1938 and he was in his mid- to late-thirties in present, then working back forty-five years, give or take five on either side, he'd have landed in 1893.
Nah, I'm pretty sure the indication was that they were sent back to the same time, 1938. So, he reached the age of 82 from there. Assuming he was 35ish (not really sure), that's 1938+47= Rory dying in 1985.
