There's also a Joseph Silverthorn(e) born c1827 Trowbridge & a tailor living in London. His wife was Elizabeth Shephard (married in Trowbridge in 1847, his father named as John, a tailor). In 1851 she is still in Trowbridge with her father & a daughter named Mary Ann, and Joseph is lodging in Wandsworth.
In 1841 Joseph is in Greenwich with an (assumed) brother, Richard. Both shown as born in county (Kent) but later census show them both as born Trowbridge. He is yet another tailor, born c1825. Married Hannah Elizabeth Selby in 1846.
As you say, it’s quite an unusual surname, so for so many of them to be of a similar age, born in Trowbridge & living in London at the same time suggests they must be somehow connected.
There seems to have been quite a few non-conformists by the name of Silverthorn(e) in & around that area, so this could explain the lack of baptisms perhaps?
