A merchant and mariner, Frank exported grain, peas and woollen cloth; he imported wine.
Frank had come of age by 1422 when he became a member of Lynn’s Holy Trinity guild.
As an office-holder, Frank was often a member of delegations that met with Lynn’s feudal lord, the bishop of Norwich, and he was one of the burgesses who visited the sick Bishop Brown shortly before his death in December 1445.
Having acted as a mainpernor for John Parmenter* and Thomas Botkesham* upon their respective elections to the Parliaments of 1431 and 1432, Frank began his own parliamentary career later in the same decade. During his first Parliament, he was entitled to daily wages of 3s. 4d., the amount Lynn had paid its representatives since the mid fourteenth century. In the end, this generous rate of pay proved too much of a financial burden for the borough and a new daily rate of 2s. was agreed upon when he and Walter Curson* were elected to the Commons of 1442. Curson set off for Westminster on 22 Jan., but Frank remained in Lynn until the following 16 Feb., several weeks after the Parliament had opened.
Apart from representing Lynn as an MP, Frank visited London on the borough’s behalf in 1439, in connexion with the King’s demands for a loan. The King had requested £100, but the corporation agreed to lend only half that amount. It entrusted the money to Frank and Walter Curson, who were in any case due to ride to London to discuss the purchase of Lynn’s toll booth from the bishop of Norwich. With regard to their negotiations with the bishop, Frank and Curson were authorized to offer his councillor, William Yelverton*, an annual fee of 40s., if he would act for the borough in this and other matters.
Although by no means a lawbreaker on the scale of his cousin John, Frank himself occasionally ran into trouble with those in authority. For example, in mid 1431 he and two other burgesses, John Holdernesse and John Nicholasson (all described as ‘mariners’) were accused in Chancery of disobedience towards the mayor and ‘insurrection against the peace’. Six years later, William Cantelowe*, victualler of Calais, sued Frank and Holdernesse in the same court. Cantelowe alleged that they had refused to co-operate when the Crown had commandeered their ship to carry supplies to Calais, and had sent the vessel to Newcastle on their own business instead.
There is also evidence for other disputes involving Frank. In the early 1430s he captured and detained a Breton, perhaps at sea, an action that provoked a quarrel with another burgess, John Boucher. The corporation at Lynn intervened, persuading him and Boucher to submit their differences to arbitration.
Late in the same decade, Frank helped to resolve a quarrel to which he was not a party, by arbitrating in a dispute over the will of his old associate Walter Curson.
