Also, I know Doyle is a common name but in 1869 when Thomas Doyle was in 14 Jane Place - next door to him in 12 Jane Place was a Michael Doyle having children too - may be a coincidence but may have been a brother and MAY be worth looking into !
There was also a Catherine Doyle from Jane Place who married Richard O'Hara in 1878 in St. Lawrence's. Her parents are listed as Michael & Anne Doyle. Again could be a total coincidence.
