The Lear, Clapp, Davis,Brignole Family

I am currently researching all sides of my family.
My mother's family includes the names Davis and Brignole. The Davis family came to this country from Wales and first settled in Ohio. They then came to California. The Brignole came from Italy and settled in Sutter Creek Ca.
My fathers family includes the names Reed, Montgomery, Lear and Clapp. The Reeds and Montgomery's are from Ukiah Ca. The Clapp family has been in the US for a very long time.
My husband's family names are Rohner and Foster. They are mostly in Lousiana.
I am willing to share any information that I have.
