There are many ways of spelling the name and I have registered the following variants with the Guild Of One Name Studies:
Hunniford, Honeyford, Huniford, Honiford and Honniford
The first two are by far the most common, with Honeyford being found more frequently than Hunniford. My father’s earlier birth certificates are Honeyford, with a later one amended to Hunniford. His father’s parish birth entry is Honeyford, while his marriage entry is Hunniford. I have even seen a marriage certificate where the Vicar entered the bride as Margaret Honeyford and she signed Hunniford !
There are other possibilities, which I have not researched, such as Hanniford, Huntingford etc. Perhaps some day.
