Hi there,
I went to Lichfield Record Office today and found your ancestor's marriage record. It says:
The Banns of marriage between Thomas Toft and Frances Brown were published on the 3rd, 10 and 17 days of January by me ? Halford, Vicar.
Thomas Toft of this parish, house carpenter, and Frances Brown of this parish, spinster were married in this church by Banns on 26 January 1768.
Both made their mark instead of a signature. The witnesses were Elizabeth Finney and ? Robinson.
This record is numbered 150. Presumably the vicar or scribe enters that number when he fills in the details. The next record, at the top of the next page, is also numbered 150. The couple who were married on this record were Samuel Rogers and Elizabeth Ridge, on 16 April 1768, by Licence.
I guess that this explains the confusion.
Hope that helps.
Ken
