Thanks to the help of several people, I can now summarise the information I've assembled. If there are any other clues to these families from any source, I would be most grateful to hear. I have concluded that Christiana Pettigrew [ aged 61 in 1851] is the mother or aunt of William Pettigrew [1819-1876+]. Selina Davies, born 1846, is my great-grandmother.
