My understanding is that the val’Horyn manifest the bloodlines that were in existence when they were created. So I think yes, some val’Holryn somewhere has been born with the val’Cessari bloodline powers. Though presumably they wouldn’t know the Cessari name, only that they inherited weird powers.
My val’Cessari character (Tukufu) claims, mostly indirectly, to be a val’Holryn. It helps that his father really was Sir Ulrich val Holryn. Its just that he takes after Mom. 
((edit: that said I don’t really know. Though I suspect the val’Holryn were created during the Blood War we don’t know their origin story or the source of their powers. It seems to me that there is enough mystery that it could easily go the other way))
