The marriage of a William Smith and Hannah Bacroft (sic) took place on the 4th Sept 1842 in Radford, Notts. William was described as a widower and Hannah as a widow. Hannah's father, John, being recorded as John Kilson.
The marriage took place a few miles from Ilkeston where William and Hannah were probably known and this together with Hannah's surname being changed to Bacroft (1) and her father to Kilson (2) appears to be to hide the fact that Hannah was still married to Isaiah Beecroft.
Although it cannot be proved that this is a bigamous marriage by Hannah nee Tilson the date fits with the Derby Assizes report (see 'Criminal' entry).
(1) There are virtually no known examples of the name Bacroft with the exception of 2 births in Essex in 1861 and 1870 and several marriages in the 1840s, none apart from Hannah being in Nottinghamshire or Derbyshire.
(2) Kilson is known as a surname with only about 17 births in the 19th century and 11 marriages, none in the counties of Notts or Derby.
