Just a quick update for anyone who followed or responded to this post I started 4 years ago in particular Monica. She stayed with me whilst jumping through all the hoops to reach my objective and gave me so much encouragement and advice.
Well four years on, I am still tying up loose ends with this part of my tree but wanted everyone to know that my research, with the help of everyone here, has been proven to be correct.
I have two DNA matches who are descendants of John Dunning the brother of my great x 4 Patrick Dunning and have been in touch with them.
I started out trying to find the death records of my x2 grandfather Duncan McKenzie and x 3 grandfather John Ferries. I had found possibilities but wasn't sure. The death record for John gave the wrong age (85) when he was in fact 56. The Duncan McKenzie death record didn't match the parents I had for him in my tree but it was my tree that was wrong. Both records were correct.
I now have burial records and locations for both of them in Greenock Cemetery. John is interred with 6 others including his wife my great x 3 grandmother Mary (nee McLachlan) two sons, a daughter-in-law, nephew and an infant buried there prior to him purchasing the Lair in1858.
Duncan McKenzie was buried in common ground and unfortunately the record does no specify where but I know it is one of three areas of the cemetery.
Robert Ferries (son of John Ferries above) is buried nearby with his second wife - the first being buried in the Ferries Lair.
My great x 4 grandparents Patrick and Sarah Dunning (nee Docherty) are also buried there with John Eadie their son in law and my great x 3 grandmother Ellen Dunning's 2nd husband who died at Graving Dock together with an infant grandson (son of John Eadie and Ellen Dunning).
My great x 4 grandfather James McLachlan (father of Mary McLachlan above) is buried with his 2nd wife Isabelle (Blair) and two sons - William and James who was the husband of Jessie McIntosh of the Sandyford murder fame. Also buried with them is his grandaughter Eliza or Elizabeth aged 3 years 6 months, daughter of John Ferries and Mary McLachlan who I had no knowledge of I have a photgraph of this grave and hope to get some of the others soon.
Unfortunately, I cannot trace my great x 3 grandmother Elizabeth McLachlan (nee McClure) as she died before Greenock Cemetery opened sometime between 1827 and 1830. That is my next challenge!
I traced Duncan McKenzie's parents marriage and subsequent baptisms of him and his siblings but haven't found their deaths yet (another challenge).
It just goes to show that if your persevere and leave no stone unturned, most brick walls can be broken down.
Many thanks once again to all.
