Brief details of his children:
- Pedigree of the Columbell family of Darley in the Visitations of Derbyshire 1569 and 1611 (as published in "The Genealogist (New Series)" Volumes 7 & 8).
- Pedigree of the Columbell family of Darley in the Visitation of Lincolnshire 1592 (as published in "The Genealogist" Volume 6).
- Pedigree of the Columbell family of Darley published in Familae Minorium Gemtium, Volume 1 page 237, taken from a variety of sources.
- "Notes on the Churches of Derbyshire", by J Charles Cox, 1875, Volume 2, page 159, within the chapter on Darley Dale church, contains the following:
[The following] account of the succession of the manor of Darley is taken from a private manuscript pedigree written about 1650, which is entitled "A true coppie of pedigree of Darley as it hath been in ancient writings recorded. (1) Robert Darley de Darley Esq had issue (2) Sir Henery Darley married to Sir John Vernon's daughter and had issue, (3) Sir Nicholas Darley married to Thomas Harthills daughter of Harthill Esq and had issue, (4) Sir Robert Darley married to Sir John Fitzherbert's daughter and had issue, (5) Sir Ralph Darley in ye green close Esq married Frechvile Baron of Crytches daughter and had issue a daughter a sole heyre and marryed to Tho. Columbell of Darley Esq"* This is an error, for Agnes, the wife of Thomas Columbell was sister and heir to Sir Ralph Darley+. Sir Ralph died in 1370.$ The family of Columbell was previously of Sandiacre, but does not seem to have been of much importance prior to the marriage with Darley. The pedigree from which we have just quoted gives four generations previous to Thomas and adds "but before these was Thomas Columbell who had lands in Codner and deeds without date"
*The book containing this pedigree was kindly lent to us by the parish clerk, Mr Anthony Fearn
+Abbre. Rot, Orig 44 Edward III, Rot 7, It appears from this document that the old service of 13s 4d, to the crown was continued by Thomas and Agnes Columbell.
