Here is what I found in Robeson County, North Carolina Marriage Bonds for 1741 - 1868:

Willis Roberts married Sally Jane Davis
14 December 1842
Bond # 000118064
Bondsmans: Etheldred Rober and William H. McNeill

William Roberts married Anna Jane Parker
15 September 1834
Bond# 000118062
Bondmand: Etheldred Rober
Witness: Edm McQueen

I did not find any Etheldred "Dred" Roberts,in any of the North Carolina Marriage data bases. I did not see a Sarah Hammond or Dicey Locklear either married to any Roberts in Robeson County. It seems that Etheldred Rober (Roberts) was a bondsman for both of these marriages mentioned above.
