English Medieval written form of John [q.v.].

• A correspondent [LA] has pointed out that many [?most] earlier manuscripts used a common script for capitals "I" & "J". Thus John may have been written and then transcribed as Iohn. Many on-line services have transcribed original documents faithfully so this version might be recorded in the indexes to earlier records.
  
  
• Another correspondent [JD²] has noted a company in the UK, 'I & H Sorby', who still use this form for John in the 21^st century.
