Thank you Judy. I did find James' obit in 1977 in Grand Rapids, Manitoba, Canada. That was quite a surprise as I thought Grand Rapids was in Michigan, and then I discovered there is one in Minnesota and finally found one in Manitoba. Anyway, in the obit it said Gladys had died in Jan 1968. I have also heard Jan 1967. So Manitoba is where we have to look for Gladys' obit.
Thanks for your help and sorry about the misinformation regarding Grand Rapids.
