Never thought of that, Prudie... our robin is apparently a different family or genus... accoding to this site "...
The American robin is considerably larger than the European robin, weighing up to 2.8 oz (80 g) with a body length of 8.7 in (22 cm), a slate-grey back, a white throat, and a brick-red breast. Young birds have a spotted breast, with reddish tinges on the flanks. The American robin is very widespread in North America, breeding from just south of the high-arctic tundra at the limit of trees and taller shrubs, to southern Mexico...

Additionally, "...
Robins are songbirds in the family Musicicapidae, in the thrush subfamily, Turdinae, which contains more than 300 species, including various thrushes, chats, solitaires, redstarts, nightingale, wheatear, and others...", Whereas "...
The European robin (Erithacus rubecula) is the familiar "robin red-breast." Robins elsewhere were given their common name, robin, because of their superficial likeness to the European robin, which to many English-speaking colonists was a common and much-loved song-bird of gardens and rural places. During the era of European exploration and conquest of distant lands, these settlers longed for familiar surroundings and contexts in their newly colonized, but foreign countries. Consequently, they often introduced European species to achieve that effect, and named native species after familiar European ones with which there was a outward resemblance. As a result of this socio-cultural process, many species in the thrush family were variously named "robin" in far-flung places that were settled by the British, including Australia, Asia, and North America..."
