Soneman was one of three sons of a minor Kentish landowner. The eldest, Robert (d.c.1448),
It was perhaps his connexion with the bridge, rather than the city, that earned Soneman his election to the Commons in 1447 and 1455, even though he appears to have joined Rochester’s ruling council. Whatever the circumstances of his return, it is unlikely that he was an unpopular choice among the citizens, not least because his sureties upon his election in 1455 were two prominent Rochester men, Thomas Cotyng* and Robert Doget*, of whom the latter appointed him the supervisor of his will of 1470.
As for Soneman’s private affairs, in July 1450 he and his family took the trouble to obtain pardons in the aftermath of Cade’s rebellion, an unusual step among the elite of Rochester but not one that implies any sympathy with the rebels’ cause.
It is likely that Soneman was old and in poor health when he made his will on 10 Jan. 1471, and he probably died soon after making it. He had certainly been unwell when surveying the manor of Grain in 1466-7: the wardens of Rochester bridge had paid for a boat to take him to Grain and back because he had been too ill to ride.
Soneman’s sons did not long outlive him. John, who continued the family association with Rochester bridge and served as its warden from 1479, was probably dead by 1481.
