bhojpuri language bhojpuri language is more similar to awadhi braj and hindi than magahi or maithili and actually i'm unable to provide any citation due to lack of proper categorisation and consideration by authorities and so there's no published record but if you want i can prove my point better let me do for example if i've to say what is you name in bhojpuri it'd be tahaar naam kaa ha in awadhi it is tahaar naam kaa hai in hindi it is tumhara naam kya hai in braj it is tahaar naam kaa hai and in magadhi it is tor naam ki helthi in maithili it'd be aahank naam ki chhe now decision is all upon you and one thing if there's no evidence on a particular point on net then the view of native speaker can be should be and must be accepted thanks
