It looks like Ezekiel had a half brother William Merriman (possibly his full name was Robert William Merriman?) - they had same mothers (Sarah) -different fathers
Ezekiel also had a half brother William Duro -same father's , different mothers
As we haven't found a marriage for Ezekiel Duro and Elizabeth (parents of William Duro b.c.1893) wondered if Wiliam was registered in Elizabeth's surname(whatever that was)
There is a birth reg 1893 for William Duro -but there is another Willliam Duro of a similar age b.Ilkeston to parents Thomas and Elizabeth.
So we don't know which parents the William Duro birth reg 1893 belongs to.
Just to complicate matters there is death reg Sept qtr 1901 for William Duro b c. 1893
So we don't know whose child died either.
I cannot find a suitable William Duro in 1911 census index -so that doesn't help either.
There were other Merriman half siblings to Ezekiel - I'll try to list them
