Coul/Kyle/Cole Names and Clan MacDowall
The names Coull, McCoul, Cole, Coyle, and Kyle, with or without the Mac, Mc, or M’ prefix, are found within Clan MacDowall. Some of these names are more ancient than the name Macdowall itself, and some appear in other clans and families also, especially in Clan MacDougall.

In its Society name, the Kyle Family Society uses the surname “Kyle” for simplicity to encompass all variations of its surname spellings and pronunciations.

In 2005 Clan Chief Fergus Macdowall confirmed that Kyle families and their surname variations, if they so wish, will be accepted as clan members as variants of the Coull, McCoul, etc. name of the Clan MacDowall. As members of Clan MacDowall these families are eligible to join the Clan MacDougall Society of North America and to participate in its games, parades, and other activities.
