Hi. Thanks for your reply to my post.
I can't fit Sarah Meagher into my tree. I can only go back as far as my 4xgreat grandfather in my O'Meagher line. That's why I have put my enquiry onto the message board in the hope that one day a O'Meagher relative will get in touch and say "These are your ancestors". I have a couple of breaks in my Kingsmill line but I'm probably distantly related to Kingsmill Pennefather and his family.
I don't know if you noticed the entry above Sarah's in the O'Meagher book. It makes mention of a William Meagher who was an attorney. I don't know if he was my ancestor. There were a couple of O'Meagher families who were lawyers, solicitors etc.
I think my O'Meaghers were all RC until my 3xgreat grandfather married Letitia Kingsmill. Interesting side note-My father was a Lane and one of my distant relatives married into the Latham family, although I'm not sure if that was their original name. William Latham came to Australia as a convict and his name on all his documentation read Laythorne.
