Christian Aaron & Ida Belle Fager Helfrich of Benzie Co., MI

I would like to hear from someone who may have more information on this family! Christian A. Helfrich was born in Jan. of 1863 in OH; married Ida Belle Fager 11 Jul 1891 and had a family of at least five children:
1) John Orville Helfrich - 25 Apr 1892 IN - 5 Jan 1982 Polk Co., FL
2) Hazel M. Helfrich - Jun 1893 IN
3) Mabel M. Helfrich - Apr 1896 IN
4) Ruby G. Helfrich - abt. 1910 MI
5) unknown Helfrich - died bef. 1910
Here are the censuses I found the Helfrich family in:
1900 census - Cleveland Twp., Whitley Co., IN
1910 census - Springdale Twp., Manistee Co., MI
1920 census - Weldon Twp., Benzie Co., MI
1930 census - Thompsonville, Benzie Co., MI
All I know is that Christian Aaron Helfrich died after the census was taken in 1930!I believe Mrs. Ida Bell Fager Helfrich died in 1949.
John Orville Helfrich married Gertrude M. ? and they had a daughter, Virginia who was born about July of 1918. Mrs. Gertrude M. Helfrich was born 20 Dec 1887 in MI & died in May of 1975 at Lakeland, Polk Co., FL.
I'd like to find out more about Hazel, Mabel & Ruby as to who they married, their families, etc. Please let me hear from you.
