Hi the only item I can find is:
Castle Lloyd Farm, Pendinewww.carmarthenshire.gov.uk/.../
[wind farm] PANELS AT CASTLE LLOYD FARM, PENDINE CARMARTHENSHIRE
More information would be a help as Lloyd and variants is pretty common and 'Castles in Wales?', there's a few of them too.
There is an active family history society that may be able to help further if this is relevant to that areawww.dyfedfhs.org.uk
