Haller Post, G.A.R., Mark Center, Ohio

When the Haller Post met in Mark Center on January 13, 1904, to make plans for their next year, they elected the following officers, according to one Defiance newspaper of the time:

Post Commander: A. N. Dunmier
S. V. - G. W. Spealman
J. V. - W. L. Brown
Q. M. (Quarter Master) - Paul Hagan
O. D. - C. S. Elder
O. G. - A. J. Byers
Adjutant - H. L. Wallace
Surgeon - O. W. Hnoch (Enoch?)
Chaplain - A. L. Hughes

One other member known was William H. Grow. 

Who were the other members of this group?  Do the post records still exist?  Although the newspaper reported this as Post #436, that number is given to a different post in the official list of GAR posts and the Mark Center Post is not recognized at all.  Was it not chartered?

So many questions - can anyone answer?
