This is an extremely unfortunate but longstanding error that continues to be perpetuated. Piers de Lutegareshale married a woman named Maud, [sic, who] also married Hugh de Boclande (I don't recall off hand which came first). Nothing is known about her parentage, in spite of the frequent claim she was a Mandeville.

In the Essex article of New Complete Peerage, a table was produced to show the descent of the title, and because Geoffrey FitzPiers and his maternal half-brother William de Boclande, married the Say coheiresses to Mandeville, Piers de Ludegarshale, Maud (no surname given) and Hugh de Boclande were placed within the table, and arbitrarily arranged in an open space under the horizontal line connecting Earl Geoffrey de Mandeville's children. No vertical line linked Maud to the horizontal line, but its absence was ignored or overlooked and many took this as asserting that Maud was another of Earl Geoffrey's children. Books like Ancestral Roots explicitly cited that specific chart for the information, yet the chart doesn't say what it is claimed to say.
