Hi Cathy, I've asked the owner of one family tree to contact you.
To find descendants, I follow the family line until I find a more current descendant's obituary.
In 1900 Ida, Henry and children were living in Corning, Tehama Co., CA. Henry McCampbell, b. CA Aug 1861, 38 yrs old, farmer. Ida M., wife, b. IA Dec 1861. Wallace, b. CA Jan 1884. Harriet, b. CA Oct 1888.
Wallace McCampbell b. Jan 23, 1884 in 1918 was living in Redding, saloon keeper, self-employed and married a woman named Ida. Source: World War I draft registration cards.
In 1920 Wallace and Ida were living in Redding but no children shown.
A Wallace McCampbell b. 23 Jan 1884, CA died 10 June 1975, Santa Clara Co. Source: California Death Index 1940-97.
You can confirm whether or not Wallace and Ida had children by requesting a copy of his obituary from Random Acts Genealogical Kindness.
The following information I found on a family tree and MAY or MAY NOT be accurate. A Harriet L. McCampbell b. 1 Oct 1888, Calif. married Dallas Arthur Bowler in 1910, CA.
Dallas Arthur Bowler b. 23 Jan 1888, Redding and d. 12 Jan 1960, Shasta Co. Harriet died 30 April 1968, Shasta Co., CA.
They had two boys Sidney H. and Lloyd A. Bowler. Sidney b. 28 March 1913, Shasta Co. He married Nelda Bernice who was born 5 Aug 1915, CA and died 13 Dec 1991, Shasta Co. Sidney died 27 March 1976 Shasta Co.
I'd request a copy of Nelda Bowler's obituary from Random Acts Genealogical Kindness. Go to www.raogk.org, read guidelines, choose California and choose Shasta Co.
After I receive an obituary, I look for survivors and then use www.whitepages.com, www.zabasearch.com or Google the survivor's name(s) to find more recent contact info.
Lloyd A. Bowler b. 12 Oct 1917, Shasta Co and died 10 May 1968 Shasta Co. The tree didn't show a wife or children. Successful Searching!
