Dockery Family History

English: habitational name from any of several places called Dockray, of which there are four examples in Cumbria. A possible origin of the place name is Old Norse d{o,}kk ‘hollow’, ‘valley’ + vrá ‘isolated place’; the first element is, however, more likely to be Old English docce ‘dock’ (the plant). Irish: reduced Anglicized form of Gaelic Ó Dochraidh ‘descendant of Dochradh’, a personal name that is a variant of Dochartach (see Doherty).
