Hi Jim,
Thank you so much for the information. My direct Pottinger ancestor is a William Pottinger (born and raised in East Ilsley, Berkshire) who married a Sarah

and their child was a son William Pottinger born in Cork, Ireland in 1805 (William Pottinger left Berkshire and went into the army in 1804 or so). I am interested in finding the Sarah he married, so I was interested in getting all the information on the Sarah White and William Pottinger marriage record in Chilvers Coton that seems to fit the best so far for some possible clues. Do you have any access to the marriage records in the Chilvers Coton area?
On another note, if your direct ancestor, William White (b. 1806), is the son of David White, you might be interested to know that David's mother, Mary (Kinder) White is from the Kinder family who lived in the area (on the same street no less) all the way back to the 1400s and beyond. I have an article on this Kinder family if you are interested.
Thank you again,
Diane
