I don't think you'll find descendants with this posting. Sometimes I have success with the following method. I find an ancestor that has seemed to have lived the longest.
Henry, Ida and Loring Heckman in 1920 were living in Eden, Alameda Co., CA.
Henry E. Heckman, b. Cananda-Nova Scotia, 57 yrs old, immigrated 1896, naturalized 1899, poultry farmer.
Ida, wife, b. CA, 48.
Loring E., son, b. Alaska, 17.
In 1930 Loring and his wife were living in Columbus, Franklin Co., OH.
Loring E. Heckman, b. Alaska, 27, father born-Canada, mother born-California, marr @ 24, mechanical engineer Gas co.
Estella D., wife, b. CA, 26, marr @ 23, substitute teacher public school.
A Loring Heckman b. 28 June 1902, Last Residence-Sun City, Maricopa Co., AZ 85351, died Dec 1967. His soc. sec. # was assigned in Ohio before 1951. Source: Social Security Death Index, www.ancestry.com.
Then I'd look for an obituary volunteer in Random Acts Genealogical Kindness. Go to www.raogk.org, read guidelines, choose Arizona, choose Maricopa County, choose volunteer.
After I receive the obituary I look for survivors. Then I try to find current contact info for them in www.whitepages.com, www.zabasearch.com or Google.
I did find other info on other family members.

I'd request a copy of his obit and see if there were any survivors. Same process as above. Successful Searching!
