From 'The History of the Church & Manor of Wigan'

[1]   ...knight, second son of Edward, third Earl of Derby, a lease of the said rectory, parish church and benefice, with the manor, park, and glebe lands, for the term of 99 years, at a yearly rent of 120; and he seems to have done but little better for the rectory of Wigan.

William Blackleach, whom I suppose to have been the next rector, paid his first fruits on 22nd June, 11 Eliz., 1569.

From certain pleadings in the Duchy Court in the time of the next rector it appears that Blackleach leased the tithes of the rectory of Wigan, for the term of his own incumbency, to Edmund Wynstanley and John Wodcocke and their assigns, who passed over their interest therein to John Assheton and Robert Worseley, of the Boothes, Esq. I learn nothing more of this rector, who resigned the benefice within two years of his appointment.

There was a family of the name of Blackleach (alias Blackledge) seated at Leyland at this period.
Bishop Huan Blackleach
(or Hesketh), Stanley's predecessor in the bishoprick of Man, is said to have been born at Blackleach Hall, in the lordship of Lathom (Leyland ?) in the county of Lancaster, and to have been the eldest son of that house.
