The only Robert Mcdowell in Raloo grave yard is as follows:
Robert Mcdowell in memory of his daughter Nancy d. 27/05/1859 aged 1yr
also daughter Nancy d. 1860 aged 4mnths, beloved wife Jane Mcdowell d. 11/04/1861 aged 42. Above named Robert d.16/04/1865, 48 years, son James Mcdowell d. 07/04/1917, 73 years. Mary Jane daughter of above James d. 18/09/1922, aged 41. Mary Barron wife of James d. 10/12/1934 aged 92.
Jane could be your Jean, as I have found other records from this area that have the name Jane and Jean as the same person
I hope this helps
