Going back to the Griffith of Bryn Y Grog. I have to post in 2 parts .
BRYN Y GROG. Griffith to Jones .
This lot are quite complicated , why did they change their name. One thing is sure all the records of John Jones selling Bryn Y Grog are not quite right, it was really John Griffith.
There are quite a few Ermin Jones around but this is the best one with an age that fits
Ruabon 26 April 1674 baptism of Ermin Jones d/o Edward Jones.
Ruabon 4 Feb 1709 burial of Ermin Jones Christionydd Kenrick. Mother of above ?
No marriage has been found between Edward Jones and an Ermine.
Marchwiel Registers . All children have surname Griffith,
1702 4 Feb Marchwiel. John Griffith yeo married Ermin Jones .
1703 30 Dec. William s/o John and Ermine Griffith baptised.
1705 12 Oct. Mary d/o ditto
1708 8 May. Frances d/o ditto
1710 17 June. Ermine d/o ditto
1712 18 Oct. John s/o ditto
1714 18 Feb. Thomas s/o ditto.
1721 2 March. A John Griffith buried.
There are no further details on any of the above records.
In the will of John Griffith, Gent, he leaves properties in Wrexham, Bangor and Marchwiel. I give to Ermin my wife one ? called Bryn y Grog to have and hold during her natural life.
And after her death I give ? to my son William JONES ( and the heirs of his body lawfully ensuing and for the want of such ) I give to my son John (ditto). I give to my son Thomas (ditto) I give to my daughter Mary (ditto) I give to my daughter Ffrances (ditto) I give to my daughter Ermin (ditto).
He gives the rest of his real estate to son William JONES and the heirs of his body lawfully ensuing and for the want of such. Same details again for John , Thomas, Mary, Ffrances, Ermin. All 6 children are named
They all are also left money between £100 and £200 . It then gets a bit complicated as regards William using more money for the benefit of the younger children. To my brother JOHN JONES and his heirs until he shall

out of the rents etc the sum of £150 ... . My will and meaning that the legacies shall not be paid to the younger children until they reach 21. All the rest of his estate he leaves to Ermin his wife.
Ermin is named as Executrix. His brother JOHN JONES is appointed as trustee.
Both John Griffith and Ermin Griffith signed the document.
It`s possible that the brother JOHN JONES is his brother in law and Ermin`s brother .
Another option is that John Griffith`s mother also married a JONES at some time , in which case he would be a step brother. It is confusing. His son JOHN would be 12.
No surnames given except for William who is now Jones , he was baptised as Griffith.
An inventory of the goods was taken on 3 April 1722.
One of the witnesses was Humphrey Foulkes rector of Marchwiel. The will was proved 24 April 1722.
1753 23 Feb. Ermine Griffiths buried Marchwiel . Her named children are now JONES.
Ermin Griffith of Bryn y Grog signed her will 11 February 1748. It was proved 4 February 1754.
She names sons John Jones, Thomas Jones and daughter Ermin Jones. Granddaughter Ermin Morris
So eldest son William b 1703. Ffrances b 1708 and Mary b 1705 are not named. Have they married, and under which surname.
It's known from documents that William Jones had definitely died by 1760 as his brother John Jones was described as his heir.
A William Jones was buried at Marchwiel on 11 May 1737 and another 1 Aug 1729 but there`s no way of knowing it`s the right one as ages and abode isn't given, also no will has been found.
Only Mary and John have been found.
