I am trying to find out about my 4X Grandfather on my Fathers fathers side a Dennis Monaghan who was born in Ireland in 1788 and who died in this country England 1869 in Keresley.

He got married and had a Catherine Monaghan who was born in Keresley about 1822.

I am trying to find out where in the Republic he was born and who he married in this country.

Also trying to find out about my 4X Grandmother on my Fathers mothers side

a Eleanor who was born in Ireland in 1776 who married a William West from Bedworth.

Would appreciate any help or advice in where to go to find out.
