Many thanks for your query to the Ireland Reaching Out message board and welcome.
It would appear that you are looking for information before 1812 with regard to William Orr and Mary Browne's origins.
Do you know if they were Catholic or Protestant?
The linen industry was active in Clonakilty in the early 1800s and it would appear that that may have been where your ancestors sought employment.
I'm going to alert one of our volunteers from this area to your post to see if they might be able to assist.
In the meantime, you might consider creating a profile of Harriett or her parents for the XO Chronicles with the information that you have. You can access that feature through the link below:
