Roger FitzAlan was a thirteenth-century Mayor of London.
[3] There has been some speculation that he could have been related to Henry Fitz-Ailwin, Roger was possibly a nephew[4][5] (son of his brother Alan), or grandson (son of Alan FitzHenry), or some other relation.
Roger Fitz Alan was close to Henry Fitz-Alwin, 'Throughout his mayoralty he was regularly accompanied by Roger fitz Alan.
There are well over 100 existing documents that bear the signature of FitzAilwin as mayor and around 70 of those also include FitzAlan’s signature",[6] given the dates it is most likely that Roger Fitz Alan was his nephew, son of Henry Fitz-Ailwin's brother Alan.
[8] Although Roger Fitz-Alan's term of office was meant only to be one year, he stayed in office until May 1214,[9] when rebel barons against John of England captured London and installed their own candidate against the King.
