Mary O'Connor was possibly from Cooltedery as Barnaby is recorded having property here in 1827[1] so there is some connection with the O'Connors from this area. Cooltedery is fairly close to Limerick and it would be a sensible connection for the mill in Cooltedery to supply a business in a major port such as Limerick.
As John was born in about 1812[2] and Mary in about 1815[3], I expect Mary married Barnaby in about 1810-1811 (no record has been found). From this her birth is estimated as about 1790. As Barnaby remarried in about 1820, it seems that Mary died sometime before this.
Nothing else is known about Mary.
