We aren't the only ones that have troubles with that long s. Before Kitty Clive got married about 1731 she was known as Miss Raftor (her father was an Irish gentleman disposessed in 1690, and moved to London). However, I've twice seen it in the 1720s spelled Miss Rastor (with long s). That v with the upward tail on the end got the librarians off the track in setting up a first line index for 'The Euing Collection of English Broadside Ballads', 1971, and they have for one first line "I habing an hour of time and leifure".
