Stirnet gives John de Cobham, 3rd Lord (d 10.01.1407-8). Sort out this old/new date - check Wiki policy.
[1] gives John de Cobham (3rd Baron) b. c1321, from the database of the LDS http://www.familysearch.org/, but they have also obvious errors about this JdeC
Stirnet gives Margaret d. 1385; Newman (Buildings of England) describes a brass in that name giving 1395 (and another brass giving 'Margaret... 1375'). Meanwhile [2] gives Margaret b. "after 1326" in Exeter. This would have made her 7 or 8 yrs old at the time of her "marriage" (and J de C only 12). Was this in fact only a betrothal contract?
