Hi Ian, welcome to Ireland Reaching Out
I can see two people with the name Edward Good living in Ballymoney co.Cork, one in the townland of Phale in 1833 and one in the Ballymoney townland of Grallah they might be related.
By 1901 there are 40 residents with the surname Good living in Ballymoney see 1901 census of Ireland http://www.census.nationalarchives.ie/search/results.jsp?census_year=19…
If you are looking for living descendants have you considdert taking a dna test?
