No. Everyone who signed the Declaration is a founding father, but not all founding fathers were members of the continental congress at that time. Take George Washington for instance. Quite obviously he is a founding father but by the time independence was declared he had already been appointed to command the Continental Army and was off doing so.
George Washington himself did not sign the Declaration of Independence. He was away at war. Most of the others did.
No, all the signatories of the declaration of independence were men.
"Founders" is the general term for the people who signed the Declaration of Independence.
John Hancock signed both versions of the Declaration of Independence. He signed the first one on July 4, 1776. That was the version that no other delegates signed. Then he signed the second version on or about August 22, 1776. That is the version that most, but not all, of the other delegates signed and the one everyone thinks was signed on July 4th, but was not.
Yes, all 44 and it wasn't a "convention " for the Declaration of Independence. The only convention was for the constitution in 1787. The Declaration was written by Jefferson because he was asked to write it and was in Congress. He was only 33 years old, but all ready had made a name for himself on the ability to be able to state what was needed. Congress voted on passage of the Declaration in October a few months after the publication of it in July 1776.
All 13 colonies had delegates who signed the document.
