looking for Tobias Gibbons born 1850

Robert:

I checked Roots Ireland www.rootsireland.ie  which is a pay site to see the actual data. There is an 1851 baptism record for Co. Mayo for a Tobias Gibbons with a father named Richard Gibbons, however, when I added Margaret Joyce as the mother, the record went away. This would mean the mothers name was different then you have. You will have to decide whether or not to pay to see this record. I also looked at the 1856 Griffiths Valuation head of household listing  for Co. Mayo for the name Richard Gibbons. There were 12 entries as show below. Looks like there may be a couple duplicates.

I will have to look further. I have a 3rd GGM Margaret Gibbos, who married John McNally and left Ireland in about 1851. John died and she remarried to Thomas Geraghty. They lived in Minooka. Later, Margaret's parents Thomas Gibbons and Mary Jane Connolly Gibbons, emigrated to Scranton
