Is “Nobiliaire de Ponthieu Ed de Vimeu - René Marquis de Belleval -google -books a reliable source

Question

I have information to contribute to the profile of Pierre Tillette. This is what I can add:

• Date of death

These are the sources I am using:

• Nobiliaire de Ponthieu et de Vimeu - René- Marquis de Belleval - google- books page 860

Should I contact one of the pre-1700 projects or know about any style guidelines before proceeding? Thank you!

Answer 1

Hi Pierre

Overall any volumes like Nobiliaire de Ponthieu et de Vimeu, that have genealogies for many noble families, but don't actually cite any sources for their information aren't considered particularly reliable.

They are particularly not considered reliable sources for pre-1500 profiles and if possible I would try to find other sources for this family.
