It seems that of the two Henry Skillicorns b.1733 & 1743 Lonan one has been lost without trace! I had just put together a hypothesis [which doesn't affect Catherine Kermode's line] but which may be relevant:
There seems to be a conflict of data between the two Thos Skillicorns who died in 1794 Lonan. Lonan MIs has "Thos of Skilco d.1741 and THO his son d.17 Oct 1794" The will of Thomas d.JAN 1794 gave him as "of Skinscoe" and was consistent with his marriage to Cath Kewley [he “fits” being s/o Thos d.1741]. The other Thomas d.Oct 17 was m. to Isabella Goldsmith. In the latter's Will / wife's Deed his two brothers ["uncles on the father's side"] were named as HENRY and JOHN Skillicorn. Thos b.1726 s/o Thos d.1741 had no brother HENRY. When it came to "Settlement Time" in 1808 HENRY was deceased and his son Thos had taken his place [sounds like Henry d.1806?]
Another Thomas Skillicorn married Isabel Cowel 1763 Lonan; she died 1784 and he re-married to Joney Kermod. They both died in June 1798 and Thomas' sons Phillip & Charles petitioned the Court for guidance re u/a children - in this petition Thomas' n.o.k were named as JOHN and JAMES Skillicorn. As far as I can ascertain [so far!] TWO Lonan Skillicorn families in the mid-18thC had siblings Thos, Henry, and John - those of John Skillicorn / Kath Skillicorn m.1722 and Phillip / Mary Garrett m.1735; but the latter couple also had a son JAMES. Thus I had assigned Henry d.1806 to parents John & Kath and NOT to Phillip & Mary. This would have Thomas Skillicorn m.1738 s/o Phill&Mary marrying Isabel Callow in 1763 then Joney Kermod in 1784, and Thomas Skillicorn s/o John & Kath b.1740 marrying Isabel Goldsmith [b1750] in 1780 at K Michael. It would also by default assign Henry b.1743 as h/o Cath Kermode.
Margaret Skillicorn als Fargher d.1820 was the wife of Henry of Ballaragh - she named all of her other children in her Will except son Henry, who was alive and the lawful heir. Henry in 1806 may have named only his youngest son Thomas for a similar reason.
It’s only a hypothesis!! – I’ve quite likely missed a Skillicorn family with siblings Thomas, John & James of suitable birth dates, or made a silly mistake somewhere along the line!
