He and his wife have duplicate daughters who are also duplicate wives to their husband, William Graham, 1st Earl of Montrose .
One has a son, William Chisholm, Bishop of Dunblane itself a duplicate, which appears to be misplaced here.
The other one is an MP, as are several others in these groups.

It seems odd for a Catholic Bishop to be married. Also the Catholic church website shows different dates for Bishop William Chisolm, who actually died 110 years later in 1564.
https://en.wikipedia.org/wiki/William_Chisholm_(died_1564)
This particular Bishop William Chisolm was the second son of Edmund Chisholm of Cromlix, near Dunblane, a son of Chisholm of that ilk in Roxburghshire, and half-brother of James Chisholm, who was bishop of Dunblane from 1486 to 1527, when he resigned his see, with the consent of Pope Clement VII and King James V, in favour of his nephew William Chisholm (II).
Bishop James Chisolm died 1545 and was evidently his half-brother and both were sons of ,Sir Edmund Chisholm, 1st of Cromlix , so he doesn't fit there either.

However, here Edmund is shown as the father of William Chisholm, Bishop of Dunblane which is another duplicate, of the above.
Bishop William Chisolm II, William Chisholm, Bishop of Dunblane is the son of William I's brother, James Drummond of Coldoch , so that much is right.
