I looked at the city directory for 1970, for the name
Robinson, Maureen G... student 51 Kingsford Cres.
but it does not match up with parents... Wm G. (Mary)
dentist-645 Hamilton Rd., h 51 Kingsford Cres.
Robinson (wm r) Margaret, wks Keeprite Prod. h. 896 Lorne Ave.
I could not find anything on Robertson. I looked in about
1958, and nothing came up there.
I really think that you should find the adoption records.
When you do.... just send me a private note with the details
and I will do some searching again.
You need to confirm the name whether it is Robertson or
Robinson as there are alot of people with these names.
Sorry I could not help you more, hopefully I can in the
