Hello Margaret,
I am researching the Wigmores from Liscarroll also, my G Grandmother was Elizabeth Wigmore, I have a little information and think that she is connected to James and Stephen. Her father was Stephen Wigmore born in 1816 in Liscarroll. Its quite confusing as the names James and Stephen seem to be very common in the family. I can try and answer any questions you may have, and maybe we will both learn something, I am in intrigued to know what this family mystery is.
