Robert,
I am descended from John Devereau and Maria Lowe - so we're on the right track! Robert Frederick Devereau was born abt Jun 1860 (after the death of his father, John Devereau which I think was abt Jan 1860). You probably know that John Devereau and Maria Lowe had 7 children (including Robert)and I have information on most of them.
Did Joseph Henry Devereau and Jane Mckibbin's daughter, Edith, marry George Taubman? This was how I thought it fitted together but I have Edith born in 1881 and dying in 1884! - I think I got this from a family tree I was given years ago.
Carol.
