Looks like Danny's family (and him) are in a pretty successful Christian band called CoastalRise. His brother appears to be the drummer and Danny performs with the band. Their Instagram account has a photo from July which says it is the Frishmuth wedding, so I assume they got married! Also, if they are a Christian band, it explains a lot of the separate houses, tight knit family stuff.
