Hello, I have a similar lineage for the Coombs family, and I am also searching for the parentage of Richard Coombs m. to Elizabeth Hubbs or Hobbs. Having done research with several Silver Book owners, there is no evidence that Richard Coombs was a son of Sarah Priest and John Coombs. I have the same lineage from Richard Coombs down to Samuel and Margaret (Langdon) Coombs/COMBS. We may be cousins.
I am beginning to think that Richard Coombs is actually descended from Archdale Coombs or Combs from Old Rappahannock, but as yet have not found any proof or citations proving this.
Hope this helps.
