Francisco was the son of Simeon Davidson, not his brother. My gr gr gandmother was Eliza Davidson, niece of Simeon, who grew up with Francisco. I have more info for those interested I can give what I have. Simeon had a brother named Benjamin (Eliza's father) and possibly Peter and Elizabeth were siblings also. Frank Davidson is buried near his father, mother, step mother and brothers in Lenawee Co, MI. I have the cemetary name somewhere also. Simeon's parents were John and Catherine Davidson. I don't know much abt them, beyond what is stated in Simeon's bio- they lived in NJ, the family was in the colonies, pre-revolution and they moved to Lodi, Seneca Co, NY around 1800 because that's where Simeon was born. Hope this helps someone. Regards, Sandy Manier
