Isabella, Countess of Atholl

Isabella of Atholl was countess or ban-mormaer of Atholl, Scotland, from the death of her father Henry in 1211 until the accession of her son Padraig in 1236/7. Two men accompanied her as effective Mormaers during the minority of her son:

It has often been thought that, after the death of Thomas of Galloway in 1232, she married again, this time to the powerful political figure Alan Durward; this however, rests solely in the fact that Alan styles himself "Count of Atholl" in a few documents between 1233 and 1234. However, as Matthew Hammond has shown, this more is more likely to refer to fact that Alan, as a grandson of Máel Coluim, Earl of Atholl, probably sought to inherit the province.
