While it is tempting to suggest that Bottenham was a scion of the prominent Wiltshire family of Bodenham, who by the 1420s held lands at Ebbesborne Wake, no such connexion has been established.
No definite evidence of Bottenham’s trade or profession has come to light, but it is possible that like his putative father he possessed some legal training, for it was perhaps in a professional capacity that in late 1424 he stood surety for the appearance of a defendant in the court of Chancery.
