I hope someone can help please.

On Brian Lawson's website there is a Jane Skillicorn DOB Nov 17 1880 Douglas:
Mother : Isabella Ann, DOB 1859/60: Father: "Not given"

In the 1881c Jane (Jeannie) is shown as granddaughter.
Finch Road, Callow Place
John SKILLICORN Head W Male 42 Lonan, Isle of Man, England Porter Shipping
Isabella A. SKILLICORN Daur U Female 22 Douglas, Isle of Man, England Domestic Servt
John J. SKILLICORN Son U Male 17 Douglas, Isle of Man, England Mason & Plasterer
Agnes E. SKILLICORN Daur U Female 10 Douglas, Isle of Man, England Scholar
Jeannie SKILLICORN Gd Daur U Female 4 m Douglas, Isle of Man, England

Is there a way of tracing who the father was?

I would be most grateful of any help given.

Thank you
