Colby, Isle of Man Colby, Isle of Man Colby () is a small village in the south of the Isle of Man in the parish of Arbory. It lies on the A7 road between the towns of Castletown and Port Erin and close to the similarly sized village of Ballabeg. The name Colby is of Scandinavian origin and is derived from Kolli's Farm which was home to the lexicographer, Archibald Cregeen (1774–1841). The word Colby is thought to derive from the Viking words Col (meaning Hill) and Byr (meaning farm). The village has a railway station on the Isle of Man Steam Railway and
Ballabeg Ballabeg derives from the Manx which means small homestead; although the spelling is different, it is pronounced approximately the same as the English name. Nearby is the "Ball and Bag", a free house which was built by Sir David Mark Jordan, a Victorian army captain who settled there upon his retirement. It also has Arbory Primary School, serving the villages of Ballabeg and Colby, as well as the outlying areas. The parish church has a large churchyard with many graves dating back at least to the mid-18th century, although there has been a church on the site for much longer.
