I am not sure of the meaning but the Surname is Swiss and there have been a LOT of variations in the spelling depending on the ability of the person to read or write and whether or not a census taker could understand an accent. For example:
Imbody, Inbody, Embody, Imboden, Inboden, Enboden, Emboden, Impoddy, Impoti etc. Hope that helps.
