Something isn't adding up?

I've been able to trace William Watson Holladay back to his previous marriage and to his parents and siblings.

I've been able to trace Rhoda from her family (parents &siblings) through her marriages.

There is a Clarence but the dates are different. I can't seem to find a Clarence Holladay born 1910 and dying in 1992 to verify dates?

I now see someone has a world connect tree which has a bunch of the family on it and at first glance I can see some of it is wrong!....
