English medieval written form of Joan [q.v.].
- A correspondent [LA] has pointed out that many [?most] earlier manuscripts used a common script for capitals "I" & "J". Thus Joan may have been written and then transcribed as Ioan. Many on-line services have transcribed original documents faithfully so this version might be the one recorded in the indexes to earlier records.
- [NB We have not seen any documentary evidence of the occurrence of Ioan but believe that the possibility should be borne in mind.]
