Hi
The widow status doesn't really alter the need to supply further information as she was free to marry presuming she was over the age of 21.
An example of a marriage allegation from 1793 involving a widow.
'Appeared personally _________ and made oath that he is of the parish of St. Andrew Holborn London a widower and intendeth to marry with ______________ of the parish of St. George Southwark in the county of Surrey widow and that he knoweth of no lawful impediment by reason of any precontract consanguinity affinity or any other lawful means whatsoever to hinder the said intended marriage and prayed a licence to solemnize the same in the parish church of Saint Andrew Holborn London and further made oath that the usual place of abode of him the appearer for space of four weeks last past has been Saint Andrew Holborn. __________'
A marriage by licence was more expensive but you didn't need to wait as long and not everyone knew your business since it wasn't announced beforehand in church every Sunday for three weeks. The cost of calling banns wasn't cheap. In 1820 (when the average Ag. Lab was earning 10s a week), the cost of calling the 3 banns was 7s. 6d. and was required in both parishes. Often either the man or the woman (whichever was most convenient, but by tradition the marriage took place in the woman's parish) would move for the three weeks necessarily to establish residency in the other parish to avoid the need for the calling of the banns in two parishes.
Marriage licences in 1820 cost 10 shillings, plus the cost of the trip and loss of a possible day's wages to visit the local Bishop's Office to obtain the licence in the first place.
