Can anyone point me to some up-to-date information about Śākadvīpīya brahmans?  What did it mean to a twelfth to seventeenth-century author to identify himself as belonging to a Śākadvīpīya family?  Would such a family have retained cultural links to Central Asia and Eastern Iran, to Seistan?  I would have thought not.  But is there any scholarly exploration of this issue?

Many thanks,
