Clare: I had another look at the Hougham Registers and found a baptims for Margaret Anne Fagg 23 October 1891 daughter of Stephen and Susanna. I can add this info on the marriage of her parents. Stephen Fagg of the parish of Eisel, bachelor and Susannah Barrowes, of this parish, spinster by Thomas Tournay, vicar on the 3rd day of April 1779. Witnesses Matthew Fagg his mark and Richard Belsey (he is the parish clerk) the bride and groom made their marks. I find a baptism for Susannah Barrows as follows 16 Feb 1852 daughter of Matthew and Elizabeth Barrows (Note no marriage in Hougham for them but their is a marriage at St. James the Apostle, Dover, Kent for the couple that you can easily find on familysearch.org. From what I found it would appear the name is acually Barrows. There are other children from this marriage in Hougham and Dover is not very far from Hougham.
Hope this will fill in some blanks for you. Now my library closes tomorrow so will not be able to view it until the new year.
