what is the meaning of the name brendan
Brendan (given name) Brendan is an Irish given name in the English language. It is derived from the Gaelic name Breandán, which is in turn derived from the earlier Old Irish Brénainn. The Old Welsh breenhin is the root of the name, meaning Prince or King.[2] The mediaeval Latin form of the name, Brendanus, has also influenced the modern English and Irish forms. Variant spellings of Brendan are Brendon and Brenden. In some cases it is possible that the given name Brandon is also a variant of Brendan. A variant spelling of the Irish Breandán is Breanndán.
Johnston (surname) The habitational surname originates in most cases from the place so called in Annandale, Dumfriesshire, Scotland. This surname is derived from the genitive case of the given name John and tone or toun ("settlement" in Middle English; tun in Old English), literally meaning "John's town". There are several similar place names in Scotland, including the city of Perth, which was once known as St. John's Toun. This and other similarly named locations may also be sources for the surname Johnston.[1] Johnston is commonly traced back to Ireland, however it is believed the name and people migrated from Scotland[2].
