These appear to be children with parents Sarah and David Humphreys ;
Ann 1/12/1824
Elizabeth 31/3/1822
Thomas 18/11/1827
Henry 19/5/1839
Mary 6/2/1831
Peter 27/11/1842
Sarah 11/12/1836
David states he is a carpenter on all but Peter's baptisms where he says he is a joiner.
On the 1851 census David and Sarah have a Sarah listed 1836 same date as the Sarah with Joseph, could be they put her down as a member of family instead of leaving her off as she was with her uncle?
There appears to be a marriage for Mary to a John Latham 25/10/1852, her father's name is David, his Joseph.
