John Williams and Sarah Aldred married 17 or 19 Oct 1910 in Manhattan. Ancestry has the New York license online but unfortunately my subs don't allow me access. So if someone could have a look for me I would be very grateful.
From FS (via FMP), only a transcription but Sarah Aldred, white, single, female age 28 b1888 father Tom mother Sarah Rosebottom married 19/10/1910 John White, white, single, male age 34 b1876 father Evan mother Sarah Davis Place Manhattan New York FS film number - 001503869 Not sure if this helps any.
Thank you @MollyMay that solves a mystery as to why I couldn't find John in the UK. John's parents were Evan Williams and Sara Davies.
