  We present the results of a search of the XMM-Newton public data archive for
stellar X-ray flares. We find eight flaring sources for which we identify 7
optical counterparts. Three of these sources have distance estimates which
allow us to determine their luminosities. Based on the decay time of the flares
and their luminosity we derive loop half-lengths of ~2-7x10^10 cm and emission
measures of ~10^54 cm^-3: these are similar to values derived for other stellar
flaring sources. One of the stars shows two flares in close succession. We
discuss the likelihood of this double event being either sympathetic or
homologous in nature. A comparison to a pair of similar flares on the Sun
suggests that homology is the more likely process driving the flare event.
