The Artful Dodger
R.I.P.
Do you know from some other source that Hughes was Charlotte's maiden name? If not, do bear in mind the possibility that Charlotte had been married before.
I think you will need to get the marriage certificate of Thomas Gordon and Charlotte if you want to trace her line further. According to FamilySearch, a Lottie Hughes married in the last quarter of 1906 in the Belfast district (vol 1, p.253). There is a Thomas Gordon with matching reference.
I agree about the marriage certificate for the one in the last q. 1906.
To me there is one problem - I have not in the past ordered certificates from Ireland. I have though obtained copies from contacts, but have lost touch with them. What is the process, please?
