the kachvai jaipur raj claims to be suryavanshi. its library contains a family tree of this line in which ram figures at 64. their calculation also appears to be based on data in valmikiya ramayan,which places ram some over 7000 years ago. the birth details of ram by valmiki appears more reasonable as he happened to be his contemporary. The story based on 28 chaturyug can be put on backburner till some new uncontrversial evidences emerge.
