I have absolutely nothing I can add to your enquiry but to say that Clara Fanny Wynn, sister to Wilfred Percival, was my Great Grandmother. She married Thomas William Henry, their daughter, Nita Myrtle Henry married my paternal grandfather, William Ewart Williams in Cootamundra in 1910. I haven't spent any time researching that branch of my tree as yet...some day :o)
