Isadore's birth and death details are only from the CA Death index
for an Isadore L. Lawlor, born in Iowa (no parents' names given).
The matching SSDI entry had a different birth year (1899 instead of 1901)
and I'm using the 1899 year because he's listed in the 1900 census as age 1.
Although he's only listed as age 19 in the 1920 census in Miller, Hand Co., SD.
