Hi Annie
William Pink baptised 23 Nov 1828 Bishops Waltham, parents James & Sarah Pink
Siblings would appear to be:
Sarah bapt 28 May 1826 Bishops Waltham
James bapt 25 Jul 1830 Hambledon
Thomas bapt 31 Mar 1833 Hambledon
Ann bapt 5 Oct 1834 Hambledon
George 21 Feb 1836 Hambledon
Joseph bapt 20 Jul 1837 Hambledon
There isn't another William Pink baptism to these parents

William Pink son of James & Elizabeth Pink baptised in Droxford 5 Apr 1835
I don't see any burials in either place which would match any of the children.
Nell
