Sudhaamaa There are several folk traditions surrounding Radha, and the one linking her to Bhoomi Devi is one such. I merely recounted some of the known traditions about Radha. If you see SP's original posting, there also she recounts this folklore that Radha extends herself as Satya. Also, there is no mention of Krishna ever marrying Radha, yet, Andal refers to Nappinnai as nadagopalan marumahal! Unless it meant marumahal as in niece for in those days, it was common for the "marumahal i.e. niece" to be the "marumahal" i.e daughter-in-law
