Janet,
I show the following marriage entry from St. Michael on Wyre:
August 18, 1777
Thomas x Hornby, Wood tp & Anne x Billington, Wood tp banns wit John Ratcliff, Agnes Houghton
I could not find Leonard Billington's baptism at St. Michael on Wyre but there is a Leonard Billington in the IGI born April 15, 1753 in Woodplumpton parish, son of John Billington, but it also shows that he died on January 12, 1758. However there is a Leonard Billington listed in several of the St. Michael on Wyre records as father of children being baptized and as a marriage witness and baptism sponsor.
