Hi Barbara, I am currently tracing my line of Collinson's in the same area as yours.
My gggg grandmother was Priscilla Collinson b 1832, to parents Thomas Collinson and Jane/Jenny Dunderdale. Thomas was born abt 1808 in stalmine but moved to Fleetwood. His parents were Thomas Collinson and Priscilla Charnley who married 20 March 1798 St mary's Lancaster Lancs. Thomas and Priscilla had 10 children that I know of Betty, Sarah, Ann, Thomas,Mary, Margaret, agnes, John, William and Jane.
Is there any connection Barbara as the names are all similar
