Although he did not take an active part in municipal life, Colclough belonged to a long-established Newcastle family, many of whose members achieved prominence in the borough as office-holders and MPs. At least four men of this surname were returned by the burgesses during our period; and even though their precise relationship cannot now be established with any degree of certainty, there can be little doubt that they were kinsmen.
Meanwhile, in January 1403, Colclough discharged his duties as a feoffee-to-uses of Robert Cocknage, a local landowner. One year later he was named in a lawsuit as the joint owner of property in the Staffordshire village of Chorlton, presumably once again in the capacity of a trustee.
