Lloyd is a Welsh surname originating with the Welsh adjective llwyd, most often understood as meaning “grey” but with other meanings as well. The name can be used both as a given name and as a surname. The name has many variations and a few derivations, mainly as a result of the difficulty in representing the initial double-L for non-Welsh speakers and the translation of the Welsh diphthong wy. Lloyd is the most common form of the name encountered in the modern era, with the Welsh spelling Llwyd increasingly common in recent times.
The vast majority of Wales continued to use the patronymic system well into the early modern period, and the families that used family surnames passed on from one generation to the next remained exceptional. However, the name Lloyd/Llwyd and certain other Welsh adjectives such as goch (“red”, evolving into the Welsh surname Gough) became “fixed epithet” passed on through the generations and functioned as family surnames as early as the 14th century.
Connections between the Lloyd family and Kilkie are that Martin Kilkie married Sarah Field, whose grandfather was the illegitimate son of Captain Frederick Lloyd from Cilcain.
