The Weld family may refer to an ancient English family, and to their possible relations in New England, an extended family of Boston Brahmin. An early record of a Weld holding public office, is the High Sheriff of London in 1352, William. In the 16th and 17th centuries people called Weld and living in Cheshire began to travel and to settle in the environs of London, in Shropshire, in Suffolk and thence in the American Colonies, and in Dorset. While most of the Welds of England had adopted Protestantism, the exception was all three sons of Sir John Weld of Edmonton, who married into elite recusant families, thus reverting, with their descendants, to Roman Catholicism. The noted Catholic Weld lineage, unbroken till the new millennium, is that of Lulworth Castle in Dorset.

The Boston Brahmins or Boston elite are members of Boston's traditional upper class. They are often associated with a cultivated New England or Mid-Atlantic dialect and accent, Harvard University, Anglicanism, and traditional British American customs and clothing. Descendants of the earliest English colonists are typically considered to be the most representative of the Boston Brahmins. They are considered White Anglo-Saxon Protestants (WASPs).
