Joseph Carson - Need a curator please and thank you

I added a profile for Joseph as DAR recognized son of David Carson and wife Elizabeth Dysart then this profile came up as a duplicate and I merged.

Now I believe the parents should be merged but the two Davids have different parents and only two children show on DAR -- Jospeh and Cynthia.

I need help to keep a family group together or divide them if there are no sources.

Thank you.
