Unfortunately the 1776 Arbory bapt in the IGI for Henry Taubman has been replaced by a member's submission (like the 1780 Malew one), if they were ever there. The Arbory one is closer to the age Henry gave in the 1851 census, and it is still a possibility. Luckily a number of bapts for the children of John Taubman & Margaret Moore are extracted entries, and are therefore reliable, and their names - including Henry - are given in Margaret's will:

It is possible that Henry was born in Rushen and bapt in Arbory, because the family must have been living in Rushen at some stage to have had a child baptised there (extracted entry from the par reg.).
This could be John Taubman's will: TAUBMAN, John 1804 Arb E 1 0106409
