I would like to clarify the information on the Nottingham rowing clubs. By 1900 there were 4 clubs I believe:
Nottingham Britannia Rowing Club formed 1869
Nottingham Rowing Club formed 1862
Nottingham Union Rowing Club
Nottingham Boat Club formed 1894 as a result of dispute over Sunday rowing
In 1946 Nottingham Rowing Club and Nottingham Union Rowing merged after the destruction of the Union boathouse in the second world war becoming Nottingham and Union Rowing Club
2006 - Nottingham Rowing club was formed from the Nottingham Boat Club,Nottingham Britannia Rowing Club, Notts County Rowing Association and Notts Schools Rowing Association but importantly not laying any claim to the earlier Nottingham Rowing Club heritage.
There is a long history of bitter rivalry between the clubs!
So the instigator of this thread should probably contact the Nottingham and Union to pursue his queries - the ideal contact might be Martin Brandon Bravo ( the former Tory MP ) who appears to be the principal guardian of the N&URC heritage.
