Margaret - Thomas Briggs Ashton was my GGFather, an Artist born in Philadelphia, probably the son of Isaac Ashton (Mother unknown), The Ashtons descended from early US Settlers, nearly all Quakers. TBA left the USA for an artists tour of Europe, met Henrietta Rossi, then married her in London. Two of their sons, Julian and George, went to Australia and became artists - Julian starting an Art School in Sydney that still exists. I dont know what became of George. The family still exists, sadly my 2nd cousin has died recently. I have no idea how the "Briggs" name became to be added to TBA. The sons added "Rossi" to their names as a compliment to their mother, who raised them after the early death of TBA in Totnes. Any info. you may have would be welcome. Regards, Bill.
