Please could anyone do a look up and tell me who were the Godparents/Sponsor of these children listed below..

Parents: Thomas Slade and Sarah Cooper. Married 2nd October 1830 Soberton, Hampshire.

I have no further knowledge of Sarah Cooper's family and hope that a Godparent/Sponsor might help me to find out more information. This has been a 10 year plus brick wall!

Richard Slade baptized in Soberton 3rd October 1831.
Eliza Slade baptized in Soberton 31st August 1834.
Alfred Slade baptized in Soberton 17th Jul 1836. (Alfred Slade was my Gt Grandfather.)
Emma Slade born 13 May 1838 and baptized in Soberton 30th May 1838. Joseph Walter Slade born 21st May 1841 in Soberton, Hampshire, Baptized 27th June 1841 Soberton, Hampshire.

(I know all about my Slade Family but not the Cooper side.)

Many thanks.
