Follow up on suggestion from Frances, I looked back one more generation in Liverpool and found James Gelling, parents William Gelling and Elizabeth Mansfield.

Jane Gelling Christened: 4 Sept 1808
Thomas Mansfield Christened: 23 June 1819
Mansfield Gelling Christened: 25 April 1827
Thomas Gelling Christened: 28 May 1826 not sure as mother is called Betsy??

I have tried to Bridge to Isle of Man from William Gelling but from my limited knowledge are finding it hard to goto the next layer down.

Regards and thanks for your clue Frances this is really a great help in the short time I have been doing this.

Regards Peter vK(Paul Gelling)
