In 1890, Manville moved to
Santa Rosa,
California and founded the Santa Rosa Exchange Bank at the corner of 4th Street and Mendocino Avenue, with Frank working as the bank's cashier. In 1903, Frank married Mary Amelia "Polly" O'Meara (1867–1944). In 1907, their son, Frankie O'Meara Doyle, was born. However, in 1921, Frankie died from complications following tonsillectomy surgery. In the aftermath of the
1906 San Francisco earthquake, which nearly destroyed the entire downtown of Santa Rosa, Doyle, an automobile enthusiast, played an important role in convincing local business owners to donate frontage space so that the rebuilt streets may be widened for the increased future usage of automobiles. As the city rebuilt, Doyle founded the Santa Rosa Chamber of Commerce to revive the local economy, and served as its first chairman. Built in 1911, the Doyle Building, located at 643 4th Street in Santa Rosa, was named for Doyle to commemorate his efforts rebuilding the city. In August 1916, Frank succeeded his father as president of the Santa Rosa Exchange Bank. In addition to running the bank, Doyle operated fruit and dairy ranches around Sonoma County. Doyle was an early member of the Redwood Empire Association, which promoted tourism in the region and the newly built northern portion of
Highway 101 with publicity stunts like the 1927 and 1928
Redwood Highway Marathons. ==Golden Gate Bridge==
