Does anyone have any knowledge of Thomas Corkhill, coastguard, born IOM approx 1796, married to Agnes.

According to what I can find out, appears Agnes was nee Agnes Southward and that they married in Cornwall in 1822 although Agnes not born in Cornwall either. By 1841 children Thomas, Matthew, John, Sarah, William, Agnes and Samuel. Family then living St Just in Roseland where seems Thomas lived rest of his life until 1868.

Especially interested in where he was born, would like to identify which Manx Corkill family he came from.

Am wondering if there is a connection between this Thomas Corkhill and my ancestor John Corkell who was in Penzance at the same time (also thought to be from the IOM).

Thanks.
