John and James Hayde were farming at Moanmore in 1827. This is an area that has no obvious connections to areas where Haydes were more prevalent at the time.
It can only be assumed that they were brothers and perhaps their father married someone from this area which caused him to move away from another area and settle here.
The location can be seen below:
John and James both had children in the 1820s and 1830s and James was still in the area when he died in 1872. There are no births in this area after the 1840s and after James died in 1872 there is no trace of any other family members in the parish, civil or census records.
Church, civil and census records are at Dunnamaggan, Kilkenny Families
I have also not been able to trace any living descendants.
