Unfortunately nothing is known of Johanna or the Lynes/Lyons family. They may have come from the Newtownsandes (Moynane) area or, given Johanna's husband's possible connection with Abbeydorney, they may have come from the Abbeydorney area.
The Lynes surname, which is most numerous in counties Kerry, Cork, Limerick and Tipperary, is an anlicisation of the Irish surname "Ó Laighin" from the word "laighean" meaning lance or spear. Another form of Lynes is Lyons, one of the commonest surnames in Ireland, particularly in the three southern provinces. In Ulster it's usually a variant of the English and Scottish surname "Lyon", but elsewhere it's virtually always the anglicised version of one of two Irish names, Ó Laighin, or Ó Liathain which possibly derives from the Irish word "liath" meaning grey. The Ó Laighin name originated in two areas, Co. Kerry and east Co. Galway. In Kerry the name was almost invariably anglicised as "Lyne". The Ó Liathain family is reputed to have originated in Co. Limerick but the Ó Liathain name is now more common in Co. Cork, particularly in the north of the county.
