MALE CHILDREN: the first born son often took the father's - father's name (child named after grandfather on father's side); second born son took mother's father's name, third born son took father's name.
FEMALE CHILDREN: the first born daughter took the mother's - mother's name (her grandmother's name); the second daughter took her father's mother's name; the third daughter took her mother's name.
From using this naming pattern I have come up with the possibility that William Brown's father may have been Hugh and Margaret Smith's parents could have been Thomas and Sarah (Sally) Smith.
SURNAME ORIGINS
BROWN: One of the "tribes" of Galway and distinguished families in Connacht -Lord Oranmore and Browne. Galway Brownes descend from a Norman - Lebrun. The Brownes first came to Ireland during the Anglo-Norman invasion in the 12th century. They first appear in Mayo as one of the families of Norman intro that wrestled the territory of Tirawley away from Ui Fiachrach tribe. From there they intermarried with the Lynches of Galway City where they afterwards became one of the tribes. This mostly Norman merchant family included Athys, Blake, Bodkins, Darcy, Deane, Fant, Frenche, Joyce, Kirwan, Lynch, Martin, and Skerret. BROWN is most common in GALWAY, LIMERICK & MAYO.
SMITH: is the anglicized version of MacGowan/O'Gowan. The "Sept" originated in County Cavan; principal Sept of Breffny which borders Co. Leitrim, Donegal & Sligo. SMITH is most common in MOAGHAN, FERMANAGH & MAYO.
LIGHTBULB MOMENT: Mayo County for Smith/Brown Connections?
In Mayo, Palmers and Carsons also found in good numbers. These are the families that left Northern Ireland together. This is also where I am searching. BUT - Smith and Brown are such a common name EVERYWHERE.
PICKREM / PICKERING - Pickrem was originally Pickering. It is of Scottish origin. I met my grandfather's first cousin and she told me she had gone by Pickrem while her brother was Pickering. It was all according to how the minister wrote it on the baptismal certificate. I expect that with the thick scottish accent it probably sounded like Pickrem.
