The 1910 census for Reed has a son William R., age 8/12ths.
But the CA Death index has Reed Charles Lawlor, born Aug. 8, 1909, with
a mother's maiden name of Cooledge. That matches with the CA Death index
record what I presume is the father Reed's wife: Ethel Dolores Lawlor, father's
surname (her maiden name) Cooledge, born 1 Jun 1889, which matches
the age of 20 given for Reed's wife Ethel in 1910. I'm guessing it
is all the same family, but I could be mistaken.
Census: 1910, Los Angeles, Los Angeles Co., California
Census: 1920, Los Angeles, Los Angeles Co., California (widow Ethel and children, with her parents, William and Mary Cooledge)
