‘Taplow’ means Tæppa’s mound, after an Anglo-Saxon burial mound.
The name comes from Old English Tæppas hláw, and Domesday Book of 1086 records it as Thapeslau. The 7th-century mound stands in the old churchyard at Taplow Court; the chief buried in it would seem to have been Tæppa. Dug up in 1883, it held weapons, drinking horns and a lyre, now in the British Museum.
