Thomas de Snyterby (died 1316) was an English-born Crown official, cleric and judge in Ireland, in the reign of King Edward I of England.
[1] He had administrative and military duties as well as judicial: for example, he was entrusted with paying for troops and horses for the war against Scotland, and with the defences of Dublin against raids from hostile clans in County Wicklow.
The parties were Richard son of Robert and Master William de la Ryvere, special envoy to the Gaelic clans.
[6] In the early 1300s, despite his clerical office, he was Constable of Castle Kevin, Annamoe, County Wicklow, a defensive fort designed to repel the O'Toole clan of County Wicklow, who raided Dublin city on a regular basis, and who burnt Castle Kevin itself twice during Thomas's tenure as Constable.
[7] Thomas stepped down as a judge in 1307, though he was still sitting in the Easter term of that year, when judgment was given in the case of Netterville v le Petyt.
