Re: Ann Carroll
Search the IFHF's online database at ROOTSIRELAND.IE. It has abt 20 M church/civil/census/etc B/M/D records for MOST Irish counties. Records before 1863 become sparse - almost non-existant before 1800.
You didn't provide any B/M/D dates.
For the name Ann Carroll there are (at a minimum) 1,673 birth, and 853 marriage records in all Ireland, for all dates. Will leave it to you to vist the database and find out which one(s) (if any) are for your ancestor.
