We present new astrometric and spectroscopic data to confirm two new M/L
dwarf systems, G124-62 and LHS5166, and discuss the nature of a third system
(LP261-75). Age and thus mass determinations of the L dwarf companions are
discussed based on various activity-age relationships of the M dwarf primaries.
This publication will update the list of widely separated substellar companions
to nearby stars.
