Susan(nah) Windmill

Hello, Susan(nah) Windmill married Jonathan Munn on 18/12/1809 at Houghton Regis, Beds. I have seen the certificate in Bedford Records office. Her parents appear to be Thomas Windmill and Ann Lawrence. They had 6 children and I am a descendant of their only son also named Jonathan (b1815)
I also have information that Susan(nah) later married a Robert Wingrave in Luton as they appear in the 1841 and 1851 census with her daughter Sarah (father being Jonathan)
