Re: my great grandparents of indiana.....
While I do not believe I am related to your Shumaker family, I do enjoy a challenge now and then.I did some census researching and found some things that may help you with your search.
1930 Memphis City Shelby County, Tennessee:
Ira Shumaker living with Eva and Carl Spiller.Ira, age56 born Indiana, Construction worker.Estella age 54 born Indiana.
1910 Memphis City Shelby County, Tennessee:
Ira Shumaker, age 36 born Indiana, Millwright/Grain Elevator, his father born Ohio.Wife: Ira E. age 33 born Indiana.Four children born/three living.Daughter: Arniel(spelling???) age 10 born Indiana.Son: Teddie D. age 5 born Indiana. Daughter: Eva D. age 2 born Tennessee
1900 Etna Township Whitley County Indiana:
Ira Shumaker born May 1874 Indiana age 26 Carpenter, his father born Ohio
Wife: Stella born Oct 1877 Indiana. Births: 1/1 living Daughter: Arniel born May 1899 Indiana
David F. Goodrich, father-in-law living with them, age 55
1880 Washington Township Whitley County Indiana:
David Shoemaker, age 49 born Ohio, Carpenter, his father born PA
Wife: Anan (spelling??) born Indiana age 34.Children: Henry, Ada, Jane, and Ira.
The 1880 COULD be Ira's parents.Problem: Ira's age is shown as 8 which could just be a mistake (would be birth year 1872 which doesn't agree with other census).Census records are notoriously full of mistakes.BUT David is shown born in OHIO which agrees with Ira's census records showing his father born in Ohio.And, the family is living in the same county, Whitley, where Ira is found living in 1900.Further research could prove/disprove David being Ira's father.
If you do not have access to census records, I can snail these to you if you are comfortable advising me of your address.
