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.
