Jacomb Family History
Jacomb Surname Meaning
Perhaps from the Old French personal name Jacqueme the Picard form of James (Latin *Jacomus) but evidence of English use of the name is lacking.
The -b- in the name would be intrusive.
Otherwise the name looks like a place-name in -comb.
None of relevance has been found but the type has probably influenced the spelling.
