Hi Sue, this one has kept me enthralled for a couple of hours, that marriage certificate would really help out!
The George Alder with an Anna was the baptism in Ampfield on 22nd August 1852, there is a death in Ampfield 6th April 1855 of a George Alder aged 2
Re census returns for him 1891 b c 1853 RG12/882/18/30 and 1881 b c 1851 RG11/1171/95/14
His occupation always appears to be a Carter, and he always gives pob as Kingsclere or on one return Kingclear.
