My 4 times great grandparents are Robert Nicoll and Christian Kinnaird or Kinnear.

I have been searching for a birth and death for Christian, but haven't been able to find any information. All I have is their marriage and the birth for their son.

Marriage:
Robert Nicoll Mason in Saint Pauls Church Parish of Perth and Christian Kinnaird in the west Church Parish of Perth. Daughter to the deceased Thomas Kinnaird of Kinloch Fifeshire,were married the thirtieth day of March,1818 by the Reverend William Mird? Thomson Minister of the Middle Church Parish Perth Perth.

Birth of their son: December 28 1818 West Church Paris of Perth.
Charles Nicoll Lawful son to Robert Nicoll Mason in the said Parish and Christian Kinnear his spouse.
Baptised the third day of January,1818 by th Rev. William Mird Thomson.

Charles Nicoll a seaman in the west Church parish of Perth married Marjory Nicol daughter of Robert Nicol and Christian Will.
Married the 28 March 1845.

I cannot find a death for Charles, but I believe he died at sea.
