Hi Nancy;
I believe Robert's son John may be the same John Garrod who is my great-great-grandfather, although I'm not sure, as I have not been able to discover his parent's name.
Do you know, was the son John born about 1845? I have no information on him from before 1871, where he appears in the census (age 26, born in Ontario), near Stayner where they lived.
