This cabinet card portrait was made at the studio of Sweet & Kinloch in Rothesay on the Isle of Bute. A genealogy of the Sweet Family in the West of Scotland identifies one of the studio owners as Charles Sweet (1864-1945). Born in Glasgow, Charles opened his studio in Rothesay in 1889 with a younger partner, Charles R. Kinloch, who was originally from there (born about 1868, according to the 1891 Scotland Census). In 1893 the two parted ways, with Kinloch moving to Glasgow. (I don’t know if the letters “N.B.” after Rothesay refer to North Bute or North Britain.)
According to the 1881 Scotland Census, Kate Sharp was also born in Glasgow. In 1881 she was eleven years old and living in Rothesay with her parents, John and Janet Sharp, and her little sister Mary. John was born in Rothesay, while Janet was born in nearby Cowal, Argyll. In 1881, John’s age is listed as 28 and Janet’s as 25, meaning that when Kate was born, her father was about 17 and her mother was about 14. John’s occupation is listed as “Draper & Clothier.”
I was unable to track Kate in census records after 1881. According to a handwritten note, Kate’s portrait was made in 1890, when she was about 20 years old. Charles Sweet, her likely photographer, was about 26.
On a personal note, Sweet is a name in my own family tree. One of my great-great-grandmothers was named Henrietta Laura Augusta Sweet. She was born in 1841 in New Cumberland, Pennsylvania, which is near the state capital of Harrisburg. Her great-grandfather, Dr. Caleb Sweet, was a surgeon in the Continental Army during the American Revolutionary War.
