Hi,
According to the source information and the entry you found on Anc..y; it refers to a marriage between Edward Hewlett, p, of South Leigh, w, & Elizabeth Ayris 13-10-1767;
Volume 4. Marriages and Banns Register [marked No. 5.] (Marriage)
Collection: Oxford: - Register of Marriages, 1559-1837
William Carpenter is supposedly bapt. Nov 1741 South Leigh and Elizabeth Ayris bapt. 3-2-in Cogges but no year is listed.
It appears as if the entries have been corrupted between Hewlett, & Carpenter something that often happens on these public trees I've noticed.
