George McFarling married Christiana Wallis in 1821 at Newington, Surrey (now London) and their first child was Christiana, b. 1822 at Kennington, Surrey. She married Richard Lee in 1845 at Newington, and one of her daughter's was - yes, you guessed it - Christiana, born 1845! This Christiana married Ebenezer Norton (as his second wife) in 1868 at Walworth, Surrey.
Back to McFarling - George and Christiana had three other children that I know of, Eliza Ann born c. 1824, Caroline born 1826 and Hester, c. 1835, in Camberwell, Surrey. If anyone has any connections, I would be pleased to hear from you.
