Peebles relatives in Fifeshire(?)

Searching for ancestors/family from Fifeshire(I believe) I am the g/grandson of Andrew Bell Peebles b1853 and Mary/Jane Mentiplay.Siblings-Archibald 1851,Robert 1855,David 1858,Catherine 1860,John 1863. Possibly all born in Pittenweem. I believe that any living relatives will come from one or more of these siblings. I have no living relatives that I know of and I must go back this far to trace other branches. The parents of these children were Robert Peebles b1815/6 Anstruther Wester and Isabella Bell. The g/parents were Robert Peebles and Helen Wallace married Anstruther Wester 1806. Any assistance would be greatly appreciated.I plan a trip to Scotland this year and it would be great to find som family. Regards, Craig Peebles.
