Hola Jacqueline,
I will respond in English as my Spanish is so unused it will be unclear, I think.
James Beaumont Neilson is interesting and as a patent holder he could be included in the Scotland Project as a notable person. Do you want his profile to be protected by the Scotland Project? You would still have control over the development of his profile as his profile manager. We could perhaps work together to provide an English translation as well as a Spanish version.
His father and grandfather, and further back, probably are not "famous" enough to be included in the Project. We try to limit the Project profiles in the post-1700 era to only those who are in some way noteworthy.
Let me know what you would like to do, and if I can help in some way.
