Chiming in a year later here, curious if you've reached any new conclusions. Coincidentally, I found this thread to decode the exact same register, from St. James. I learned in an article about Penelope Aubin by researcher Debbie Wellen that this church was infamous at the time for performing 'clandestine' marriages. In Penelope Charleton and Abraham Aubin's case, the match was not approved by the bride's mother or biological father (Sir Richard Temple, 3rd Baronet!). However, Henry--the first name only listed at the end--was the name of one of Abraham's brothers, perhaps a witness and/or bondsman as was suggested. Hope this helps solve your mystery, too. Please let me know if you've unravelled any more insight since these posts. Thanks!
