Radcliffe is probably aged 1 in 1881c s/o Thomas Duggan (age 33 born Arbory) + Eleanor Radcliffe (born Maughold - I'm sure Sue will fill in her genealogy) - Thomas is a Carrier living near several other Duggan families on Malew Rd Arbory
Thomas is I think s/o James Duggan + cath Gelling age 3 in 1851c. (james age 27)
James I can't immediately find in 1841 but is I think s/o Thomas Duggan + margt Callow - this family is I think at Ballanorris in 1841c with Thomas age 40 and also at Ballanorris in 1851 with Thomas age 53 but no bapt found for him tho states born arbory
