As it's Wednesday went to library & archives....
From the non-conformists' records of Little Staughton baptist church.
birth 2/3/1777 James, son of William & Mary Lugsden of Little Staughton
birth 18/9/1806 Robert Williamson, son of blank & blank Lugsden of Little Staughton
birth 22/1/1797 George son of William & Mary Lugsden of Pertenhall
birth 5/11//1799 Mary daughter of William & Mary Lugsden of Pertenhall
birth 21/3/1805 William son of William & Mary Lugsden of Pertenhall
If these entries are the basis of the IGI extracted entries how come they have Robert with correct birthdate, but don't mention the 'Williamson' bit & then contrive that his parents are William & Mary.
So we have 2 families of William Lugsdens, one in Little Staughton & one in Pertenhall; This does tie up nicely from the 1803 Muster Lists, where the one in Pertenhall is class 2, a farmer age 31 with 2 children under 10; and the one in Little Staughton is class 4, a husbandman.
Also found a book in library about the Little Staughton Meeting House by H G Tibbutt, published in 1951 & it states that eight persons joined together on 10 June 1766 to set up the baptist church in Little Staughton, which included William Lugsden, Mary Lugsden, Ann Lugsden. Later James Lugsden joined the congregation, & William with James & William Peppercorn established the church.
So as the Lugsdens were baptists, does this explain why their marriages were done by licence ?
more on that later
