Richardsons of Manchester, England ca. 1760's

I am searching for descendents of Thomas and Frances ( nee Aspinall ) Richardson who were married in Manchester Cathedral on July 20, 1761.They had four children in Manchester: Thomas b.Dec.02,1764; Mary Ann b.?; Elizabeth b.?; and Frances b.June 08,1776. Frances married my gt.gt.grandfather Jonathan Scarth in Manchester Cathedral on June 08,1797. Are there Richardsons out there connected to this line?  David
