according to family search he was Born 9 dec 1883
but registered in March quarter 1883 http://www.freebmd.org.uk/cgi/search.pl
I think we could assume he will be born 9 Dec 1882
died 18 July 1961 Wanganui, Wellington, New Zealand
2nd? married 1905 to Alice Cornish from corbridge Northumberland lots of children.
Henry is a hard person he should be easy to find but is not! assume he is not using his name from birth at that time?
I think one option is just order his birth cert from this site http://www.gro.gov.uk/gro/content/certificates/default.asp
