Allan derives from "aluinn," meaning fair or handsome.
The Allan surname (spelled with an "a") is associated primarily with the Scottish Clan Ranald of the McDonald Clan (i.e., Clan Donald). Additionally, it is associated with Clan MacFarlane, Clan MacKay, and Clan Grant. Sons of the Chief of Clan Grant took the surname MacAilean (Gaelic) but eventually converted that to Allan.
The Allen surname (spelled with an "e") is considered an English surname. In Ireland and the Hebrides, the Gaelic name MacAileain is commonly anglicised as both Allen and Allan, with and without the prefix. There have been matches in our Family Tree DNA project between Allan's and Allen's, indicating common ancestry.

This Family Project is started to:
1. Help researchers on common or related families work together to find their common heritage (See the Patriarch Page)
2. Identify the DNA of the ancestor families and compile them and their lost branches into distinct genetic lineages through DNA matches
Surname DNA testing is the newest tool available to genealogists. These tests help genealogists verify their paternal ancestry (father's father) in a quick and easy way. It saves time, prevents mistakes, and provides invaluable data that can be obtained in no other way.
