Hi Wendy,
Are you sure about these dates? For example "Margaret Skillicorn b 1797 Lonan". William Maddrel and Margaret Skillicorn married 12 Dec. 1812 which makes this date look unlikely.
Their daughter Ann Maddrell was bapt 20 Nov. 1814 Lonan.

How did you trace the different parishes which the connecting families came from?

The William Moore & Ann Maddrell 1837 marriage in Maughold doesn't give additional details, such as a parish for Ann. There is a Maughold burial for a William MOORE aged 52, of Lewaigue, 28 Jan 1850. The family was in Folieu in 1841. An infant Daur of Wm MOORE was buried March 3 1843.
