As the surname by which he was commonly known in England indicates, Walsh originally hailed from Wales – more specifically, from Glamorgan. It is not known when he was naturalized, but in an undated petition for denization, directed to the Commons, he claimed to have been resident in England for 30 years and more, and he may have had denizen status by 1429, when he apparently owned property in Dartmouth.
As Walsh’s association with some of the leading men of Dartmouth demonstrates, these illicit activities did not damage his standing among his fellow townsmen. In the autumn of 1430 he was chosen one of the bailiffs of Dartmouth, and not long after he was named among a group of some 42 men from the port who allegedly assaulted the royal escheator, Baldwin Fulford*.
By 1429 Walsh had occupied a house in Dartmouth which adjoined that of the former mayor and MP John Foxley†, but his works to improve the property became the subject of a bitter dispute between them, which had to be put to the arbitration of other burgesses, including John More II*, Hugh Yon* and John Rede I*, in the court of the mayor, Thomas Asshenden (later Walsh’s companion in Parliament). His main residence aside, Walsh also owned another tenement, as well as a garden ‘above the towne’, and in October 1436 he rented the cellar beneath the house belonging to John Bridon for a term of ten years at an annual rent of 11s. 4d., probably for use as a storeroom.
Walsh is not known to have had offspring other than a daughter who died in 1441,
