seriously I think talking about Crimea "Nukes" Heron there will reap more rewards than on this board. There it is a name any serious researcher will recognise. Im sure there must be people there who know far more than I about this family.
At the very least people could point you in the direction of whats been written about the family in the Journals Of The Gypsy Lore Society.
As to whether they married according to gorjo laws, as opposed to their own laws. I find this is an approximate ratio after 20 yrs of research: Baptism very likely to find. Marriage about half the time, burials hardly ever.
