I am researching the O'Neil's who lived in the Stormont Dundas Glengary county. My understanding is their home was somewhere in the Cornwall area.
My greatgrandfather was named Edward - he married a Mina (Elmira is another name that pops up) Kyer in that area. He had the following children: Evert (known as Roy W. - born 1908 and worked as a police officer and detective in Ottawa), Ernest (a boxer?), Lloyd (lived in Hamilton), Allan (presumed the youngest) and A SISTER NAMED GLADYS. My grandfather was able to speak French as well as English.
I am wondering if there may be a link with Gladys O'Neil as this name was not common then.
