Any idea of the years involved before I can help look for information.

The Westmeath telephone book has 3 Griffin and 7 Coughlan's with addresses of Athlone. That's 10 letters if you want personal information.

There is just 2 Griffin's in Westmeath in 1854:
Only 1 in the Union of Athlone (within 12 mi.)

Joseph Griffin, Parish of St. Mary, Townland Hillquarter
Union of Athlone, tenant of John Ennis

17a house, outbuilding and land 6 acres 1 rood 27 perches

There are Coughlan's too but not in Athlone or Union of Athlone:

Patrick Coughlan, Parish of Drumraney, Townland Carrickaneha
Union of Ballymahan, tenant of Eleanor Casey

3a house, outbuildings and land 8.1.30
............................................................

Lawrence Coughlan, Parish of Drumraney, Townland Orr

(this means another generation with a Luke Griffin this fellow probably born 1840's, the problem is the jumps between available information)

After 1864 civil registration occurred and you can get
a copy of a birth certificate from the General Registry Office, Dublin www.groireland.ie

Westmeath & Roscommon both belong to an Irish History Foundation with baptism and marriage records, it is a not for profit but fee paying website, Parish records and civil records to 1900.

Griffith Valuation:

Luke Griffin, Parish of Aughrim, Townland Cloonfamore, Union of Carrick-on-Shannon, tenant of Henry S.P. Mahon
#6a house and land (pt bog) 11 acres 2 roods 15 perches

Luke Griffin, Parish of Drum, Townland Newton,
Poor Law Union Athlone, tenant of Rev. Jas. R. Moffit

1Bf house and shared land (part bog)

If more than 1 house, its two different people as if the property was only for the land, the house would be rented out.

I have to go now, grandkids to school.
