Hi Josie
Don't know where in Italy the Butti family came but I can tell you that Elizabeth Mitchell, who was 1st married to John Nollie, then married Louis (Lewis) Butti was born c1805 in Edinburgh. Her parents were John Mitchell (tinsmith) who died between 1851-1855, and Agnes Wilson, who died 12.2.1855.
John Mitchell was my 4th G Grandfather.
In 1841 Louis Butti was listed as an Optician, then in 1851 he was down as a Carver & Gilder.
Hugh Home signed both Louise & Elizabeth's DC
