Per https://www.vulture.com/2015/12/finding-raffi-c-v-r.html Raffi and Deb divorced and never had kids.
As unconnected profiles i don't think anyone else can edit them even though some are Public(?).
Maybe your collaborators could?
I started this thread from the father's profile rather than Raffi's because even as a curator i can not start it from Raffi. Even as a curator i could only edit Raffi's profile if you asked me to do so on your behalf.
I had a laugh at one websites description of Raffi as the world's most popular children's singer. I have 3 kids (teens and 20s) but have never heard of him until today.
