Hello We livenear Sarnia, Ontario, Canada. My grandfather's name was Earl Duncan Mcilwain. He left Canada for Detroit on or about 1929 during the depression. My father is Garland Mcilwain (80years old). He never seen his father as we were told he went to Unites States. We believe he would have started a new family since he was so young when he left here. Every now and then we try to find where he went but have had no luck. My great grandfather had many brothers and sisters. If you believe that you might have your grandfathers come from Canada. let me know or give me a name of the oldest Mcilwain you have and I will look it up here. Thanks Christine Mcilwain (daughter of Garland and Pat Mcilwain)
ps. My grandfather grew up in Alvinston, Thamesville Glencoe area.
