Constance Radcliffe wrote "Gilbert Radcliffe was taken by Dr. Shaw to be a younger son of Ballaradcliffe, and was first entered for Intacks 43 and 44 (as they were numbered in the eighteenth century) in Andreas in 1625. He married Margaret Kinry (Harrison), and had two sons, James and John, and two daughters, Bahee and Katherine. The two sons received his various smallholdings of land, James taking the oddly-named Belfast, with the West Croft near Ballavarry, and John receiving Crot e lough (intack 44)".
See Dr Shaw's article on Manx Notebook. [Story of an Old Manx Northside Family 'Radcliffe y Sundher' of Andreas By R. CUNLIFFE SHAW, M.Sc.. F.R.C.S.. F.R.Hist.S., from the "Ramsey Courier” of Wednesday, Dec. 24th. 1952].

There are numerous other messages about this family in the archives of this board. There is one where I put census entries at: tinyurl.com/72uzewp
I had put Lough Farm before being corrected later.
I see you were part of that thread!

If you do a "Search" using the words Radcliffe Belfast you will find many other messages.
