Do these names sound good together?

My sister is having a baby boy. She is naming him Zaniel. She wants to give him his father's middle name and his grandfather's middle name as his middle name. Their middle names are David and Ray so his name would be Zaniel David Ray. She wants to know if those names go good together. Please no rude comments and no other suggestions because she is set on the name Zaniel. (No, it isn't a typo... It's Zaniel with a Z not Daniel lol.)
