kashyap as default gotra (ritual manual?)

[Benjamin Slade]

Some time ago, I came across a reference somewhere that in case of a person's gotra being unknown, for purposes of marriage etc., they should be assigned Kaashyapa gotra.

I can't recall where I saw this reference and Google hasn't been of any help. So I was wondering if anyone could point me to the source(s?) for this custom.

(Intriguingly the rsi Kashyapa seems to be connected with "conversion" of Mlecchas, e.g. in the Bhavishya Purana).
