Hello Keith
Mine are the poor Scruttons too. But I think another branch of poor Suffolk Scrutton mariners to your branch of poor Suffolk Scrutton mariners, as I don't have a George born 1791 in my tree! Mine tend to be more Falkenham than Ipswich based (not that they're far apart).
My contemporary to your George is Jeremiah Scrutton, born 7 April 1794 Falkenham who moved to London, presumably in the 1830s (his second marriage was to Harriet Gardner 4 Nov 1838 at Holborn St Andrew's. Jeremiah's second son, William Scrutton (25/3/1841-10/10/1904), who was variously a cellarman, a dock labourer and a wine porter, is my great-great grandfather.
I managed to pick up a copy of the book about the wealthy Scruttons (The History of the Scruttons by AE Jeffrey) a few years ago, which was quite lucky as it appears not to have been published as such, but printed for private circulation. The wealthy Scruttons descend, according to that book, from Robert Scrutton (1730-1809), a tailor in Ipswich.
According to the tree printed in that book, Robert Scrutton's youngest son James Scrutton (1768-1804) moved to London in 1783 and was one of the founders of a stockbroking company, Ellis, Scrutton & Co. He married Susannah Urquhart (1769-1823): the Urquharts were in shipping. They had a son Thomas Scrutton (1799-1867), whence all the Scruttons through the 19th & 20th centuries to run the shipping businesses.
