MX, which is the claim you think needs an in-line citation in the footnote? That mom rajawongse is an honorific title, or that his name is Pia Malakul? Personally, I don't see it as making a claim, but just an explanation for readers who may be familiar with Thai names (but is pretty much common knowledge for those acquainted with Thai subjects). --Paul_012 (talk) 13:33, 8 October 2018 (UTC)[reply]
