Thank you QueenoftheWest, Milliepede, jonw65
The only child I have found so far for William and Hannah Langley is
Benjamin Langley, Baptism Date: 27 Jun 1667. Baptism Place: St John of Wapping Tower Hamlets Middlesex England.Father: William Langley, Mother: Hannah Langley
London Metropolitan Archives; London, England; Reference Number: P93/JN2/004
The marriage record indicates she was a maiden.
I will investigate the William and Ann baptisms in Aldgate/Cripplegate area 1618-21.
Thanks to you all for your replies
