This Robert is suggested by Marian Pratt in the Hougham/Hurley family record.
According to Arthur Hougham in his record, Robert of Elmstone (born ca 1423 and shown here as the son of this Robert) is the son of Simonus (died 1370). He verifies this by reference to MS27 in the College of Arms.
This Robert is included to assist future researchers to determine the accuracy of either histories.
Family Search has a Robert de Hougham born abt 1395 at Elmstone, Kent who may be this missing link.
