Dignam Family History
Dignam Name Meaning
Irish: from Gaelic Ó Duibhgeannáin see Dignan . English: of uncertain origin. Reaney and Wilson suggests this is a habitational name for someone from Dagenham formerly in Essex now in Greater London which gets its name from an Old English personal name Dæcca + genitive -n + hām ‘homestead’ but this is implausible.
