I started checking out this problem, but had to go, so have come back and edited my answer....
By GEDMatch, you do not match either of the Kendalls (Donald is Cynthia's father). However, you do match 10.5cM on chromosome 2 with Ted Cash. He is a 4th cousin, once removed thru John Eddings.
Ted Cash though shares 26.6cM on Chr 17 with both of the Kendalls. Ted Cash and Donald Kendall are 3rd cousins through Andrew Blackburn (1811-1889) Andrew Blackburn, which has been confirmed by DNA.
It's odd because you have the same relation to both Ted Cash and Don Kendall (4th cousin once removed thru John Eddings), and while you share 10.5cM DNA with Ted, you share none with Don.
So, I am beginning to wonder if you have have another relationship to Ted Cash or if it is just spurious match. 10.5cM is after all not much of a match.
In conclusion, I can not confirm the relationship of yourself to Eddings using available DNA information. I guess it's possible, but can not be confirmed.
Also, small world! ...we ourselves are 11th cousins (in theory) and I'm also an 11th cousin (in theory) with Ted Cash. Both of these relationships though are well beyond the limits of autosomal DNA testing.
