I came across this thread when I was looking into John St Clair and Ellen Fogarty, parents of Florence St Clair. I noticed some gaps re the children of Florence and Carl G Sundstrom. Florence and Carl had five children - Thelma, Bertil, Elvira (my grandmother), Henry and Violet. Thelma did not have children but as far as I'm aware, all her siblings did. I also drew a blank when looking for more details about John and Ellen, as has another member of the Sundstrom family when she worked on this some years back.
