On 10 May 1837 Mary Ann Underwood signed an affidavit indicating her desire to marry one William Wright. Mary Ann was recorded as a Spinster, of adult age, (twenty one), and she was able to sign her own name. William signed his own version of the document, in which it is noted that he was a bachelor and also an adult. Mary Ann's purported age at marriage is almost three years more than her actual age, if the her date of birth is correct.
