Hello Andy. We've corresponded before, but maybe not about Wat(t)ers.
This Lawrence Waters had a brother, Peter Waters, who married Elizabeth Lecadit Watson of Cellardyke in 1904. She was a second cousin of my grandfather Watson, who went to the fishing with her brother James Watson ("Patchie"). Have you seen any of the books about the fishing industry in the East Neuk written by the late Peter Smith of Anstruther, native of Cellardyke and long-time maths. teacher at Waid Academy? In his book "From the Sma' Lines and the Creels to the Seine Net and the Prawns", Pete describes how, in his early student days at St. Andrews University, he was a bit overawed by university life and too poor to indulge in the high life like some of his fellow students, so he spent a lot of time with the fisherfolk, especially with Peter Waters, a friend of his father's, and Peter's "Dyker" wife. Like a lot of St. Andrews fishermen, Peter Waters had a sideline in caddying on the Old Course and once caddied for Bobby Locke, who tried unsuccessfully to persuade him to come back to America with him.
My great-uncle Henry "Harry" Duff, whom my father and I were both called after, was brought up in the fishing community in St. Andrews and his stepfather William Bond was a seaman turned golf caddy, so I suppose that was how he got his start. Harry became a golf pro in Nashville, Tennessee. My uncle John Watson followed him out to the States after WWI and became a pro in South Bend, Indiana, where for a time in the late 1920s my father was his assistant, before coming home and going to the fishing.
Another Waters/Watson marriage - Thomas Waters of St. Andrews (s/o Thos. Waters and Catherine Anderson) married Ann Watson of Cellardyke (d/o Wm. Watson and Mary Doig) in 1881, on the same day that James Brown of St. Andrews married Elspeth Robertson of Cellardyke.
Sorry, getting a bit far removed from your original query here!
