Large H II regions formed by rich OB stellar associations are suspecte
d to be sites of SN explosions. In most cases, the characteristic emis
sion of the resulting supernova remnants (SNRs) is masked by the stron
ger H II region emission. In those cases, other SNR identification tec
hniques are required. Here we present the application of one of these
techniques (kinematic identification) to the detection of several SNRs
inside the large H II regions N19 and N66 in the Small Magellanic Clo
ud. Similar observations are suggested for galactic nebulae of similar
properties.
