A detailed spectroscopic survey of chemically peculiar (CP) stars in the
Orion OB1 association is the most comprehensive observational program in the
field of stellar magnetism that has been carried out at SAO so far. As at the
end of 2018, we have completed surveying CP stars in the oldest subgroup
$textit{a}$ of the association. In this paper, we give a short overview of CP
members of the subgroup showing both direct and indirect signatures of
multiplicity. Among the overall 11 stars which had been classified as peculiar,
we found several good candidates for further detailed study.
