Lois Ralph has done a huge amount of research into Lonan Skillicorn families, much of which is available online, including on this BB. Use "Search" for the widest period given to find her dozens of messages (as "Lois"), and many Skillicorn descents she has posted.

mostly transcribed by Lois.

If you post the Lonan family you are looking for, giving full details of the generation which you are absolutely certain is correctly linked to you (from original records: parish reg., censuses, wills, etc.) she might see this message and offer help. But first see the many records I've suggested which are already available.
