Hi,
Are you a member of Ancestry?
There is a tree on there that says -
John Richard (26/10/1760 -3/1832) and Ann Parry (1777-20/3/1860) with ten children - all born Llanerchymedd - Robert, Elizabeth, Michael, John, Ann, Mary, Catherine, Jane, Richard and Margaret.
Is this the family?
If so Ann Parry's forebears seem to be -
Michael Parry (1748-20/8/1813) born Plas Llanfair, Mathafarneithaf, and Ann Owen (1752-1816) born Bodwrdin, both died in Llangwyllog. Three children Catherine, Elizabeth, and Ann.
Richard Parry (1702-17/5/1755) - born at Pendref and Ann Davies (1710-21/1/1784) - born Plas Llangwyfan. Seven children - Ann, Mary, Perry, Richard, Owen, Michael, and John
Owen Parry (1675-14/4/1732) - born and died at Pendref, Rhodogeidio, Llanmerchymedd and Margaret Evans (1676-27/4/1731) - born Ty Mawr, Llanynghenedl. Seven children - Richard, Perry, Mary, Barbara, Margaret, William and Owen.
Thomas Parry (died 1722) and Heiress Pendref. Three children John, Richard and Owen.
There seem to be more details but am now on my way out.
I'm sure this will whet your appetite.
