Glen/Glenn

Glen/Glenn was accepted by CDSNA as a sept in December 1988 based on its being noted as a sept in the 1954 publication Badges of the Scottish Clans.  This sept name has a strong connection with Agnew above.  Also listed as a sept of clan McIntosh.

Relationship to Douglas undocumented.

The most likely reason for this surname’s inclusion as a Sept of Doulgas is that it could be (arguably) a shortened form of Glenndinning.  Research time was devoted to determining the veracity of this assumption but nothing of substance was found.  Perhaps future research will shed more light.
