John and Eliza Catherine were the grandparents of Noreen Cottier who was a long-time member of IOMFHS and one of the first I "met" on the internet many yrs ago when I started IOM genealogy--actually I got to know her first thru snail mail.
Anyway, I have lots of info that Noreen shared re: this family.
Please contact me at djdorca@comcast.net and perhaps I can fill in some of the blanks for you.
Also interested in the info that you have.
Regards,
Donna
