Re your post.
I note your mention of the PENTLAND surname.
Of interest to you may be the marriage of Dinah GRIMASON to John PENTLAND, this marriage happen on 10 Jan 1864 at Lurgan, Armagh, Ireland.
As for your Ann Grimason whom Married John WARNOCK on the 17 Nov 1825 I have now established who her parents are.
They are William GRIMASON and Elizabeth GRIMASON nee MULLEN.
Since you appear to be a Descendant of William and Elizabeth GRIMASON I can tell you that you do have many distant relations 3rd & 4th Cousins scattered around the World that I know of in the following countries;
Australia, England, Ireland, France, New Zealand, Scotland and USA.
If you visit my website at http://grimason.one-name.net/pg%20001.html
click on the Sitemap and the go to page 59 and then click on the link to the Grimason/Grimeson/ Grimison Pedigrees of the World you will then be taken into a sub website where you will need to click on the name Index and in your case you have two options either Select M or W for either MULLEN or WARNOCK.
You will find that this pedigree is rather extensive.
