Question: Who is the paternal grandmother of Thomas Stewart (Bishop Of St Andrews)?
Sentence (from "Robert II of Scotland"): Marjorie had died probably in 1317 in a riding accident and parliament decreed her infant son, Robert Stewart, as heir presumptive, but this lapsed on 5 March 1324 on the birth of a son, David, to King Robert and his second wife, Elizabeth de Burgh.
Relevant evidence: No
