Susan Viell Berkeley (Fitzalan) - Duplicate Susans

This profile for Unknown Profile seems to be a duplicate for Susan FitzAlan. Both are married to James Berkeley, of Thornbury, but they have different parents.

One is the daughter of William FitzAlan. The other is the daughter of Thomas FitzAlan, 17th Earl of Arundel.

William FitzAlan is supported by Tudor Place:

Thomas FitzAlan, the 17th Earl does not appear to have a daughter Susan:

Any objections to merging and setting her father to William?
