Page 9 of De Lacy Bellengari's "The Roll of the House of Lacy" states
"Robert's wife was Matilda Countess de Perche."
De Lacy researchers will know that this 1928 work has had a lot of its
assumptions overturned by later research, but I have never seen this
particular statement challenged in a subsequent work.
Matilda (d. after 1154) wife of Robert de Lacy is not identified by modern
sources, Early Yorkshire Charters, etc. I think we need a cite to a specific
document before we can believe the identification. By your own statement other
things in this work have been challenged. Negative disproof at that time is
almost impossible. You're mainly left with charters, deeds and Continental
records.
