George Thomas Orlando Bridgeman, The History of the Church and Manor of Wigan… (1888)
“ The first indubitable Parson, or Rector, of Wigan [1] that I meet with is Ranulf, Treasurer of Salisbury, who, as a non-resident, appears to have nominated a vicar or perpetual curate to serve the church in his place. On 12th June, 1199 (1 John) , a grant was made to Adam, clerk, de Frekelton, of the perpetual vicarage of the church of Wigan, at the request of Ranulf, Treasurer of Salisbury, Parson of Wigan. ”
