Searching for Gr-gr grandfather David Rhino/Rino/Reno.

Baptised David "Rhyno", 1830 Nova Scotia, Canada.

1860 Federal census, David "Rhino" is residing in Ellis Co, Texas.
David "Rino" enlisted March 1862 as a Private in Milford, TX with Col. Speight's Texas Infantry, Capt J.L. Halbert, 15th Reg't, Co E.
His last Company Muster Role is dated May & June 1863. He was "Present". Remarks section states he was a Detl'd Brigage Teamster. This info is from NARA.
This regiment had engagements in 1863& 1864 at Stirling's Plantation, Teche Campaign, Bayou Bourbeau, Red River Campaign and the Camden Expedition.
He is David "Reno", Private at Camp Speight,pg 110 of the book "History of Navarro County" by Annie Carpenter Love.
He has not been found in Pension records.
His wife remarries in 1868 in Ohio. There is no record of divorce for them in Ohio.
Two of his sons, Edward & Cummins Rino, eventually make Texas their home and raise families there.
I would like to find the exact date & place of death and where he is interred. Any suggestions will be much appreciated.
Thank You
