Igoe

Philig:

I searched on the subscription site Roots Ireland and located a December 6 1833 marriage between James Igo and Rose Ann Mahon at Killoe RC parish.

I also found three baptismal records in Killoe for children Ann 1834 Catherine 1839 Thomas 1842 There was also a record for a John in 1837 but the mother was shown as Bridget.

Many Igoes in Killeter in the 1901 census of Ireland:

James Igo in Killeter is shown in the 1854 Griffith's Valuation of Longford. Note there is a Mahon family on the same page.
