A tree on Ancestry has this pair, but only has Leonard G Blackwell born 1912 as their child. This could mean that he is their relation and they haven't bothered with siblings.
They give the marriage as 24th July 1906.
David's parents are given as Alfred Blackwell 1857 - 1933 and Louisa 1859
Eleanor's parents are given as Thomas Baker 1842 and Eliza 1861
Thank you for the information. I'll search for them in freecen and freebdm.
