There are 16 Brennan girls recorded as participants in the Earl Grey scheme which took young destitute girls from Irish workhouses to Australia 1848-1850. The original list (highlighted) is the work of Trevor McClaughlin and more detail can be accessed at http://www.irishfaminememorial.org/
My research was done on Griffith's Valuation which is a record of all landholdings in Ireland c1850. I attempted to match Trevor McClaughlin's information with the townlands and Civil Parishes of Ireland in the 1850's. Please feel free to use this research but if you use it please acknowledge the source. If you have identified the family of any of the Brennan girls in Ireland, I would love to hear from you.
