There's a bit in Edward H. Milligan's Biographical Dictionary of British Quakers in Commerce and Industry, in his article on William Hoyland, that adds some detail on Barbara. It reads (in part): "He married in 1787 Barbara Wheeler (1764-1829). Of the eight children recorded in Quaker registers, three sons and two daughters survived to adulthood. Barbara Wheeler had been brought up in the Established Church and (her parents having both died before she was out of her teens) she lived for a time with a family where she became 'unhappily entangled in the specious snares of scepticism and infidelity' (Testimony). When, however, at the age of 21, she visited friends in Yorkshire, she came to see these views as 'the innovations of folly, false philosophy and vain deceit' (ibid. She resumed church-going and, as she was not a Friend, the marriage was of neccesity 'before the priest'; for this William Hoyland was disowned by Balby MM. Their first years of married life were at 'Myrtle Bank', Handsworth Woodhouse, east of the town. In 1790, while in Sheffield itself and unable to get to her usual church, she attended Sheffield meeting and, later becoming convinced of Friends' principles and method of worship, was accepted into membership in 1792, her husband being reinstated shortly afterwards. Her gift in the vocal ministry was acknowledged by the monthly meeting." She moved to Bradford a few years after her husband's death.
Milligan cites the Testimony of Brighouse MM concerning Barbara Hoyland, in 'Testimonies concerning ministers deceased', v.350-3
On a personal note, William Frazer Hoyland, son of William and Barbara Hoyland, married my 1st cousin 5x removed, Hannah Walker.
