Major John Montgomery of Crogan died 1679
Colonel Alexander Montgomery m. Elizabeth daughter and heiress of Colonel Thomas Cole of Ballyleck prior to 1696 and died march 25th 1722 leaving several children. It was probably early in this century that Alexander and his cousin appeared to have disused the Hessilheid arms and to have adopted the sheild of the Montgomeries as carried by the Earls of Eglinton,adding thereto instead of the scottish crest an arm in armor the hand grasping a broken spear and for a motto instead of the scottish "Guarde Bien"
the new words "Patrise Infelici Fedelis"
