Relatives of Fredrick and Ann Veronica (Cannon) Coons?

I have been trying my best to track my paternal grandmother's family line, but I'm hitting a block both ways. These two had my Grandmother and enumerable amount of child one of which my grandmother, Katherine Francis Coons (still living in Mechanicville, NY, attend Mech. HS along with husband Wallace Edward Mallery Sr.). Any information on this line would be greatly appreciated.
