Thanks Ian. What's a PR?
I've found the record for Henry born of Richard and Pamela in pilot.familysearch.org. It lists a Baptism/Christening in 1851 at LAVERSTOCK, WILTSHIRE, ENGLAND, and a Birth in 1831 at same (Laverstock, Wilts, Eng). Google maps doesn't show me a Winburne, but does seem to indicate it's near Salisbury. Laverstock shows as a relatively new area in Salisbury. Could these indicate the same area and person?
This conflicts with the 1851 census that shows Wilscombe, Dorset (or Wivelscombe, Somerset)? I wonder which piece of info is reliable?
