Research Notes:

While not named in his father's will, there is reason to think he was the elder brother of Lawrence. Thomas Senyclas or St. Nicholas of Thorne, who married Julian, daughter and heir of Nicholas Manston, by Eleanor, daughter and heir of Edward Haute, in his will dated 1474, names his mother Bennett (i.e. Benedicta) but not his father. In a pedigree by Vincent (Philipot's MS., Coll. Arm., Nos. 26-27, p. 37), which commences with the father of this Thomas, the Christian name, John, has been added in pencil by the younger Vincent. Whether we may rely on this evidence or not, as to his Christian name, we cannot doubt his immediate descent from Sir Thomas St. Nicholas, as we find his sons bequeathing estates, which they could only have derived from the heir of Sir Thomas. One of these sons was named John, we may fairly assume after him; he being himself baptised John, according to the prevalent fashion of the times, after his maternal grandfather, John de Goshall. The other...was named Thomas, after his paternal grandfather. ¹
