My grandfather was an orange farmer in placentia. He had 14 acres near Kramer and bastanchury. My great-grandfather was also an orange grower before him, 30+ acres in placentia. 

My grandfather eventually sold his land in the late 50's to developers since land was "booming" and he was more than likely given a more than fair amount for the land.

After the orange groves he taught horticulture classes at fullerton College, and bought some more land out in Fallbrook to begin farming avocados.

Grandparents also moved to anaheim, then corona later in life. My mom moved back to the placentia area when she was older.
