I live in Hamilton,Ontario,CANADA. I was born and raised in NEWFOUNDLAND,CANADA. I am 55 years old;married;3 daughters. I know of only one other GRENFELL as a first name. The only other time I knew of GRENFELL (as a Last name),was Dr.Sir Wilfred GRENFELL,who came over to Newfoundland from England in the first half of the twentieth century,where he established a hospital at St. Anthony. The surname WARREN is a very popular one in Newfoundland,and,indeed,throughout Canada,and the U.S. Where are the origins of these two names ? Thank you for ANY information.
