Pattee Family in Ottawa Ontario

I'm attempting to obtain information on the Pattee Family in Ottawa, Ontario.My gggrandfather, Col Gordon B Pattee was a 19th century timber dealer who built an home at 149 Somerset St W.in Ottawa in 1891. I believe the home is now a heritage property. Either he or his predecessors are believed to have come from Concord, NH. He had three children to the best of my knowledge, a son Harry G. who eventually moved to California; a daughter, Eva Caroline, who married Fred W. Carling; and a daughter (name unknown)who married Charles Berkeley Powell and had two daughters, Evalyn and Marjory. Any additional information on this line of the Pattee family will be greatly appreciated
