Isidro

Isidro is a Spanish form in the Isidore name family, from Greek elements meaning gift of Isis. Isis is the Egyptian goddess named in the older compound. This ancient religious reference remained part of the name’s linguistic history even as the name became established in Christian communities.

San Isidro, the patron saint associated with Madrid, gives the Spanish form a separate Christian and local significance. A family choosing Isidro may therefore be honoring the saint or a relative rather than the ancient goddess. Isidoro is a longer related Spanish form, while Isidore is familiar in English and French. The different forms preserve the same underlying name family.
