For a John Lawlor and Mary Sanford marriage, Co. Laois, 1862 +/- 4 yrs, I found 0 rcds in any parish. This infers: 1) Some of your info may be wrong. 2) The records didn't survive (most likely). 3) The rcds haven't been transcribed. Or 4) They married elsewhere.
There is a B rcd for a Thomas Lawlor in 1863, with a father forenamed Patrick, Ballyfin RC parish, Co. Laois.
