Portrait of Lord William Beauchamp Nevill father

I I'm lucky to own a copy of this portrait of Lord William Nevill, the first Marquis of Abergavenny and father of Lord William  Beauchamp Nevill.

Mother in law

Lord William Beauchamp Nevill married into the wealthy Murrieta family. This beautiful portrait is of his mother in law who sadly died shortly  after he was sentenced to five years penal servitude

Lady nevill in widowhood

When lord nevill died his wife left her h o me to move into the hotel Rembrandt where she stayed till her death in 1951. The Rembrandt is opposite the Catholic Brompton oratory where lord William Beauchamp Nevill had his requiem mass held. However there are no burials here. Where was lord William Beauchamp Nevill buried ? Will continue to seek the answer to this question
