John -- I just found your web site. My great grandmother was Margaret Sophia Eacutt (note spelling), daughter of Isaac Eacutt and Sophy Rouch.
They lived in Morrisburg in the 1870s when Margaret married by great grandfather Reuben Brown. I haven't been able to trace what happened to the rest
of this branch of the family and if you have any idea, I would like to know. I think they probably emigrated to the States, but am not sure where.
Do you know what branch of the family Isaac was descended from?
Found your site very interesting.
Cheers
