It's hard work isnt it haha.
The Find a grave post says hes born in Cork
Not really...
The problem is Timothy was RC but his wife Hannah was Anglican, so where would they have Married?
With a Family Crest/Pedigree there MIGHT be a Marriage Agreement, more so due to mixed Religion, BUT normally from Bride's family to Groom's. (Grantor to Grantee)
These (attached) are, e,g, Horan to... 1730
's for example! Wills/Deeds/Marriage Agreements, etc. Will look later/tomorrow to see if any mention Roscarberry if no one beats me to it!
But Who to Hogan ?? grrrr!
These are later 1700's
