Henry Taubman was still alive in 1851, living with son George and family at Mill St., Castletown. Described as weaver? (retired), b.Rushen. His age was given as 78 (60 in 1841). I can't find either burial or will for him. IGI has only submitted bapts around those dates, but the 1780 Henry said to be b.Malew has the correct marriage date for him, and father John.
