Can you identify these relatives?

Below are some verified photos of Elias and Sarah (Brown) Locke.  This first photo may be the same couple.

Could this be Elias and Sarah (Brown) Locke?

They were married in 1845 and would have been 24 then. This original is printed on heavy paper which is consistent with calotypes, invented in 1841.  Calotypes were not as clear as daguerreotypes (1837), but multiple copies could be printed on paper.  The back is marked "E. H. Keney, Photographer, 406 E. Fifth Street, Dayton, Ohio." 
Follow-up internet research: 

Erastus H. Keney was born in New York about 1838 and was active in Dayton from 1870 to 1900.

Answer: No, this is not Elias and Sarah, but could be a photo of one of their children.

These photos are identified as Abraham and Rebecca (Ott) Lock, parents of Elias (above).  Could someone verify this?

Abraham Locke (b. 6/20/1794; d. 9/15/1872)

Rebecca Ott Locke  (b. 9/28/1794; d. 11/6/1869)

 Parents of Abraham Lock?  Don't think so.

This photo is identified as the parents of Abraham Lock ( John Lock b. 7/4/1755; d. 10/4/1818); Salome b. 1755; d. 12/24/1840), which is impossible since the daguerreotype wasn't invented until 1837, calotypes in 1841, and tintypes were not common until about 1860.  This looks more like a Touby face to me. 

Is it possible that this is Peter Touby and his mother, Anna Marie Slout Touby?

Is this George Luther Locke?

Are these Locke brothers?  Compare to the brothers above.  

A couple of them could be husbands of Locke women.

I think this is Antrim "Bud" Locke

These images were in the same album and could be Locke sisters or wives of Locke men.

Information on the back of this photo:

J. Nicholson, photographer.  Over Darnall and Scotton's Drug Store, Main Street, Kokomo, Ind.

Pictures copied enlarged and colored in every style.

Research: Nicholson was born in Franklin, Indiana (2/12/1866) and was engaged in painting in connection with cultivating fruit and later learned the art of daguerreotyping.  In 1872 he moved to Kokomo, Indiana and from there, in 1879, to Crawfordsville, where he opened an art gallery.

This tells us that the photograph was taken (or copied from the original, as the ad states) between 1872 and 1879.

Are these Locke children?
