My Simpsons sem to work - but thet dates are slightly out and one name a bit different?

My Alexander Simpson is my g,g,g,grandfather -married to May Stewart on 29th November 1850 in Kilconquhar, Fife. They had 5 sons (possibly 6), one of whom was Robert, born 20th February 1862 also in Kilconquhar, Fife.

If this fits, please let me know. I have a lot of history!
