William Love

I assume this families were Protestant. If so, marriages from 1845 onwards were recorded in the statutory records. I have searched those records for Samuel Love’s marriage to Ellen Mundell in 1850 without success. There were a couple of Samuel Love marriages around that time but not to anyone named Mundell.

Statistically, Alice’s surname is probably Esler (268 Esler in Antrim in the 1901 census to 24 Estler). The vast majority were Presbyterian (so Scottish origins).

Birth registration only started in 1864. Prior to that you need to rely on church records.  Not all church records have survived and not those that have survived are on-line. I have searched rootsireland for the family but without success. It’s possible that the records are in PRONI (the public record office) in Belfast, on microfilm, but you would need to have some idea of where they lived to have much chance of tracing them.

Possibly DNA testing may be a way of matching with others who have additional information about where the family originate. Family Tree DNA reportedly has more people with Ulster roots than any other company. That obviously increases the chances of finding a match. You might want to try them or, if you have already tested, you can transfer your results to them for no fee.

The North of Ireland Family History Society are running an Ulster DNA project and can offer FTDNA testing kits at a reduced price.  http://www.nifhs.org (Go to DNA project on the website).
