Kefa on Family Tree Circles

My grandparents are Welsh, Scots, English and Irish.

My father : Alwyn Ernest Pritchard.
His parents: Ernest William Pritchard and Evaline White.

My mother: Mary Winifred Purtell .
Her parents: John Joseph Purtell and Ethel Emily Tanner.

Grandfather Pritchard's parents: Frederick James Pritchard and Florence Elizabeth MC Quoin.

Grandmother Tanner's parents: Stephen Tanner and Emily Stower.

Grandfather Purtells parents: Michael Francis Purtell and Margaret Prout.

Grandmother Whites parents : James White and Jane Smellie.

How much can a man write? Frederick was a cabinetmaker/ carpenter who had several premises in Melbourne. I have the source of his origins in the London area. But there is no evidence of his location after his divorce.
He is my paternal great grandfather of the Pritchard line.
This maybe could for a start.
