We search for the production of doubly charmed baryons in ${e}^{+}{e}^{\ensuremath{-}}$ annihilations at or near a center-of-mass energy of 10.58 GeV, in a data sample with an integrated luminosity of $232\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ recorded with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center. We search for ${\ensuremath{\Xi}}_{cc}^{+}$ baryons in the final states ${\ensuremath{\Lambda}}_{c}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ and ${\ensuremath{\Xi}}_{c}^{0}{\ensuremath{\pi}}^{+}$, and ${\ensuremath{\Xi}}_{cc}^{++}$ baryons in the final states ${\ensuremath{\Lambda}}_{c}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}$ and ${\ensuremath{\Xi}}_{c}^{0}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}$. We find no evidence for the production of doubly charmed baryons.
