Since your last name at birth is "Minter" and your looking for more of your relatives, I believe you might mean the One Name Study Project. If so you can find more information and how it works here:
Basicly one would create and maintain a Project Free-Space Profiles page for a particular surname for the use of communication, posting pictures, research notes, publication and internet sources, tables and any other helpful tools. Then you would add your surname category to your project so that individuals with that surname would add their profile to it.
We do not have a specific one for the "Minter" surname but if you wanted to start a study you would follow the instructions listed in the "How to Create A One Name Study Project Page" paragraph and go from there.
The leaders of this project are Douglas Lockwood and Alison Andrus. They would be glad to answer any questions you may have concerning the project as a whole.
Hope that answers your question!!
