Catherine is my second great grandmother.

The Rehill name was carried on downwards i believe as a middle or first name on the female side of the family as Reaell, Raiel, Raiell and even Rae. When researching Ii have discovered many spellings for the Rehill name (eg Rahill, Riehl, Rials, Reil, Ryle, real etc)
