Many thanks for your post to the Ireland Reaching Out message board and welcome to the site!
I have forwarded this query to several of our Donegal volunteers who may be able to assist you. You might give them a week or so to reply.
In the meantime, your ancestor Charles McLaughlin would make a great ancestor profile to the XO Chronicles (tab at the top of the page). Many of our members have created ancestor profiles for their family research. These profiles are updated weekly and read widely by all members. There has been a lot of success stories from members who have been able to share and collaborate with others researching the same families. If you have any difficulty creating one, please email me at: email@example.com.
Thank you for your interest in Ireland Reaching Out and the very best of luck with your research!
