I'm trying to find more, or any, information on a man, surname Petterson, who died during a regatta in South Africa sometime in the early 20th C., possibly around 1911. Unfortunately I do not have his first name, but his body was apparently bought ashore on to the Kalk Bay beach.
He was married; unfortunately I don't have his wife's name either. They had at least two children - Gertrude Elizabeth Petterson (c.1908 - 1980; she married Wilfred Hampshire; later she married Umberto Poletto) and Margaret Martha Petterson (d. 1988; she married James Eagles).
I have reason to believe they might also be related to an Andrew Petterson and a Charles Petterson (possibly died 1952). Andrew and his wife Lydia had at least two children - Andrew Charles Lewis Petterson (b. 1941) and Anita Ursula Petterson (b. 1946).
Any help you might be able to provide would be greatly appreciated.
