My G.G.Grandmother was Margaret Corlett who married Hugh (Ewan) Gill in Lezayre 24/7/1831. Hugh was also a Miller at Milntown.
Do you have her in your tree?
Also have you noted many "inter-marriages" between the local Millers families. I am also related to the Curphey's who were Millers in Sulby and the Claddaugh.
