Hi Mark,
I'm sorry I can't help you with the older Spaldings. At the moment I have the 1861 census, parish of Peebles. Perhaps you already have this:
William Spalding, unmarried, was living at Eastgate end, Peebles, 64 yrs. His occupation was Landed Proprietor and he was born Manor, Peebles.
In Northgate, Peebles Thomas Spalding, 62, Nurseryman
Grace, wife, 40; James, son, 14; Margaret, dau, 4; Grace, dau, 2; W.G., son, 1m;
all born Peebles.
