Yes, he did! But he didn't have any children by her so she raised her sister's children and didn't have any of her own. Then 18 years later Mary Ann died and William Henville Burford married again six months later but outside the Messent family this time.
And that's not all that happened in this family - it happened with the Samuel Stokes, too. Eliza died and so Samuel married her younger sister Letitia Messent! Letitia did go on to have 4 children by him so she raised her sister's 2 surviving children and hers!!
A bit strange it happening twice in the same family. So out of 4 sisters there was only 2 husbands!
Also, the information you just gave me shows Mary Ann as being the witness at Elizabeth's wedding and then she ends up marrying the groom!
