I hope that in researching the history of the Caldwells & Calwells from Lochwinnoch, Scotland, that someone would look at the notes of Andro Crafurd [Andrew Crawford], author (ca. 1836) "The Cairn of Lochwinnoch." Crafurd identified the tenants and subtenants occupying land in Lochwinnoch of Paisley Monastery, beginning in the 1300s. He also described the landlords of the who were particularly oppressive. Crafurd mentioned, for example, that in the Charter records of Paisley Abbey there is a summons at the instance of Robert, Abbott of Paisley, dated January 1504, against members of the Orr (Or) clan, John, Alan, Ninian, and Johnne. The Abbott charged the Orr clan members, "pro injustis intro mifsione, occupatione, laboratione, et manoratione terrasum", Latin for occupying land and putting the populace in fear.)

Plunkett Caldwell may be able to affirm that planter Hugh Montgomery induced James Orr and his wife Janet Clement from Lochwinnoch to settle in the townland of Ballyblack, near Newtownards, Co. Down ca. 1607. Their success in relocation may have led to their neighbors, Alexander Colewell and Andrew Calwell, purchasing land in 1614 in Donegal from Cunningham.

In 1972, Ray A. Jones produced his work "Ulster Pedigrees. Descendants in many lines of James Orr and Janet McClement who emigrated from Scotland to Northern Ireland ca 1607". This book may reveal intermarriage between the Orr and Caldwell clans
