Looking for Ancestors of Robert Robertson Honeyman

Robert Robertson HONEYMAN was born on Dec 21st 1868 in Edinburgh. He became Chief Engineer of the Irawaddy Steam Navigation Co in India, dying there in 1914.
A possible geneology has his father as Thomas HONEYMAN, born 1832 in Leuchars, Fife; his grandfather as Thomas Hill HONEYMAN, born Dec 3rd 1797 in Ceres; and his great Grandfather as Thomas HONEYMAN, born Feb 16th 1771 in Ceres. I am particularly looking for a family link between those aforementioned and Thomas John HONEYMAN, born in Glasgow,10th June, 1891.
