Rhoda Ann Usher (Wilmot) - Henry Usher and Rhoda Ann Wilmot

Rhoda Ann Wilmot 27/4/1852 was NOT married to Commandant Henry Usher 4/11/1842 but to my Henry Usher 8/2/1846
Marriage Certificate no 161 Wesleyan Chapel Bathurst 23/8/1870. Please look carefully if you enlarge it, age Henry Usher 24 age Rhoda Ann Wilmot 18
Age 1870, Commandant Henry 1842 (28), My Henry Usher 8/2/1846 (24), was NOT Commandant!
I have also compared my Henry Signature on Rhoda's DN, his brother's Jonah Alfred DN and Marriage Certificate
Then from a reliable source it stands on Commandant Henry's Memorial in Umtata that he was NEVER married. I have personally not seen it.
Yours Sincerely,
Allan Vincent Usher
