 Arnold became one of the 13 original proprietors of Providence , and his initials appear second on the " initial deed " signed by Roger Williams in 1638 , following the initials of his son Benedict 's future father @-@ in @-@ law , Stukeley Westcott . He was assigned a house lot on what was later North Main Street , but his stay in this part of Providence was short . About 1638 he , his wife and children , his son @-@ in @-@ law William Carpenter , his nephew Thomas Hopkins and a few associates and all their families moved four miles ( six km ) south to the Pawtuxet River , at the far southern edge of Williams 's Providence purchase . They settled at the ford where the Pequot Trail crossed the river , close to where the Warwick Avenue ( US Hwy 1A / Hwy 117 ) bridge later crossed the river in the town of Cranston . Here Arnold remained until the end of his life . Though in some deeds he continued to be called " of Providence " after his move to Pawtuxet , this was before a dividing line had been created between the two localities , and he physically resided at the location called Pawtuxet .
