Constance Cheney/Cheney was a daughter of Thomas Cheney & Philippa Hinstead. Her brother Richard Cheney was an Ironmaster, as was her first husband William Relfe.
With William Relfe, Constance had three known children; Richard, Bennet & Anne.
William Relfe died in 1582, leaving Constance to administer his estate. A series of complex leases, unpaid rents and debts lead to a complex court case in 1591. By this time Constance was married again to James Hobson. Also involved in the case was her husbands cousin Gregory Relfe & her brother Richard Cheney.

Reflections on the Role of the Sussex Ironmasters in Elizabethan Glamorgan
By John O. Morley
p. 5. Among the first Kent and Sussex ironmasters who had interests in Glamorgan were Sir Henry and Sir Robert Sidney of Penshurst, Est Sussex, William Darrell of Scotney, William Relfe of Mayfield, Anthony Morely of Glynde and Thomas Cheney of Cralle. ...p.9. One of the earliest references to the activity of the Sussex ironmasters in north Glamorgan comes from an updated Bill of Complaint (thought to be 1572) issued by an Edward Lewis against Jeavan Howell, William Relfe and William Darrell and in which he alleges that they had deprived him of his rightful lands, a watermill and tenements in Llanwonno which he
was entitled to as an inheritance from his deceased grandfather Ryse/Reece ap Morgan who died in 1564. This claim arose because Edward's father, Lewis ap Ryse, had predeceased his father , Ryse ap Morgan, leaving Edward, the only son (who was an infabt at the time of his grandfather's death) as the legitimate heir. In his action, Edward claims that after his grandfather's death (which he says was about 8 years before his petition), the defendants entered his lands and one of the tenements with force and ejected him. Furthermore, they stopped and diverted the flow of water to a grist mill and erected an iron furnace with trenches and ditches there which had resulted in the utter destruction of woods, meadows, pasture and arable land. In his written defence, William Relfe refuted the accusations, saying he regularly paid an agreed rent of 5 pounds 13s 4d. per annum for a lease on the property which had been aquired by Jeavon Howell by a deed from Reece ap Morgan dated 17 February 1564. Morgan died shortly afterwards and it is thought that Relfe and his assosciates siezed control of the lands, constructed the furnace a few years later and subsequently built of acquired two forges for processing the cast iron into wrought iron. The result of this action is not known, but the fact that Relfe and his partners were still holding the land and furnace at the time of his death about 1582 (see later) suggests that it was either unsuccesful, or they agreed to compromise. .... He ( John Morley) reports that William Darrell, William Relfe and Anthony Morley were the owners of two forges of Ironworks in Llanwonno. The forges, as well as a furnace which belonged only to William Darrell and William Relfe [1570s]...[Anthony Morley]His creditors included Constance Relfe (the widow of William Relfe and daughter of Thomas Cheney)...she was owed 400 pounds [p11]... Meneffee subsequently paid Constance Relfe a total of 600 pounds for her estate, but unfortunately, he did not receive the appropriate deeds, leases, and other documents relating to the forges or properties for which he paid. After his deeath, his widow, Elizabeth Meneffee, who had subsequently married Robert Martin of Aberdare around 1589, petitioned Sir Christopher Hatton on 16th October 1590 to force Constance to hand over the deeds/leases. In reply, Constance, who by now had married James Hobson, denied that there was any agreement between her and Thomas Meneffee that she should hand over the documents requested. She also denied that she had detained and of the writings/evidence as alleged by Elizabeth. This acrimonious dispute between Robert Martin & Elizabeth (formerly Meneffee) his wife (the complainants) and James Hobson and Constance ( formerly Relfe) his wife (the dependants) was further pursued in the court of Requests at St Nicholas in Glamorgan on 24th Sep 1591 before Thomas Wiseman and Griffith Williams ( the commissioners)..
p.14 Following the death of William Relfe in 1582, Constance his wife was awarded his thirs part of the ironworks which he owned in Glamorgan by a Mr. Appesley and she in turn granted her share to Anthony Morley as described earlier. However, these assets appear to have reverted back to her after his bankruptcy in late 1585, because the transfer had been conditional on Morely paying her 100 pounds per year rent which he had failed to do so for four years and she was owed 400 ;pounds...
The genealogy of William Relfe, the other sussex ironmaster involved in Glamorgan is well known & described comprehensively bt Llewellin. He was married to Constance Cheney who was the daughter of Richard [Thomas?] Cheney of Cralle, another prominent Sussex ironmaster. ...
