Unfortunately nothing is known of Johanna or the Lynes/Lyons family. Given that Johanna's husband, Myles Cunningham, was from Newtownsandes (now called Moyvane), it's possible Johanna may also have come from this parish. In case Johanna's family came from the same townland in Newtownsandes as Myles, i.e., Kilbaha, here are details from marriage and baptismal records located on the Irish Genealogy website, www.irishgenealogy.ie, for a number of people with Lynes connections who lived in Kilbaha. Note that the Lynes surname is interchangeable with Lyons.

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.
