Who built the Byrnes houses?

After the "Looking Back" column, Whonnock's Aunt Hill appeared in The News, 8 August 2007, I received a call from Margaret Matson (née Leaf) telling me that not Winnifred Gordon, but a Miss Rogers built the two Byrnes houses for herself and her sister, a Mrs. Davies. Miss Rogers must have sold the houses to Mrs Gordon since Byrneses acquired them from her and not from Miss Rogers.
