The farmhouse sits back from Marsh Creek Road down a long private drive, invisible from the road and tucked into the middle of 200 acres of stone fruit orchards in the flat, sunbaked farmland of Contra Costa County. By October, the peaches and apricots are done for the season, the crews have moved through and the property settles into the quiet after the harvest. Emily Courchesne, 37, had helped out with her uncle's business since she was a teenager, selling at farmers markets across the East Bay.
