Can anyone help with information regarding the above and his family?

Arthur GRIFFIN b. 1751 Newbury Berks, m. Sarah STRONG 1775 St Mary's church Kingsclere Hampshire
They had the following children -
Charles Strong 1775 Bapt. St Mary's Kingsclere

I have only been able to find details of Edward 1799-1872, I have nothing regarding Arthur & Sarah plus their other children.
Who were Arthur's parents and what happened to the children?

Any help appreciated.
