I noticed this morning that a James Lugsdin Bailey emigrated to New Zealand in 1850 (see
http://www.angelfire.com/az/nzgenweb/diaryjlb.html ) and thought there must be a connection.
He was born at Datchet, Berks, on 22 July 1827, son of Ann and
William Bailey. In the link above he mentions his Uncle Lugsdin
Marriage 10 Aug 1807 at Holborn: James Lugsdin bach of St Giles Cripplegate &
Esther Bailey spinster of St Andrew Holborn. Witnesses: Joseph Harrip & E Jacques
Marriage 20 May 1828 in the City of London: James Lugsdin widower of St Nicholas Brighthelmstone Sussex & Martha Lidgould spinster. Witnesses: Ann Newbery;
William Bailey (was this his first wife's brother? Probably, as in 1827 William Bailey named his son for James, and it seems as though they were still close in 1839 when James was involved in arranging the schooling of William's son James Lugsdin Bailey at the City of London school)
In 1841 William Bailey was a baptist minister in Datchet
I think this helps establish the link between the first two marriages. I think William and Esther were siblings
