I have info on the Viveash family, my grandfather was Reginald Charles Oriel Viveash B 1884 in London.
I have the original document granting a coat of arms to an Oriel Viveash, grandson of Simeon Viveash of Calne, Wiltshire in 1838 solicitor to the East India Company.
I also have a few brass buttons with the family crest which would have adorned the servants uniform
Please contact me for any info that may be of use to you, and any thing that may help me.
