Hello Sue, Thanks for this,

you said - As Constance Radcliffe labelled her chart "Glen Vullen (Mill Glen)" surely they are the same place?

yes, that is what I am trying to find out, also in 'A History of Kirk Maughold ' it says - GLEN VULLEN (known as Collom’s Croft)

and in their Book it says,

Maughold and Ramsey Place Names by William and Constance Radcliffe.

GLION (Y) WYLLIN Glen of the Mill

Glan vollin Lib. Canc. 1647
Glan vuilling EF 1768
Glen Wyllin NSS 1841

A croft, part of Ballachrink, near Cornaa Mill.

are they all the same place with just different spellings ???

Thanks,
Averil
