Manard is not labeled on the 1971 Topo map
Manard is shown on the 1905 Oklahoma Premier Gazette map where the highway from Tahlequah croses Bayou Menard, Population 10. H-46 on the map if you must.
This road appears to be rt 10 / 62 currently
The 1902 Railroad survey of Indian Territory shows the Cherokee Central Railroad running from Tahlequah to Ft Gibson along what appears on the 1861 map as the road from Talequah to Ft. Gibson. This does appear to run north of current 62.
The 1861 map also shows the Cherokee Agency at or near Tahlequah on the Illinois River. Interestingly the 1861 map is more accurate than either the Mayo 1882 or Maxwell 1889 maps regarding the postion to Talequah NE relative to Ft. Gibson. Both those maps show Talequah essentially due east of Ft. Gibson.
Mayo 1882 map shows Manard roughly halfway between Bayou Menard and Green Leaf Cr on the Road between Talequah and Ft. Gibson.
The best hint though comes from Fitch's 1898 map which shows the best geometry to actuality and shows a road from Tahlequah past the Cherokee Men's Seminary winding down along Bayou Menard to Manard again located about where Rt 10 crosses Bayou Menard. The Cherokee Seminary appears on the South 62 about 3 miles from Tahlequah and I wander if it is not the site of the second displaced Agency.???
Now the fun part, looking at Fitch's 1898 map it appears the road runs north of Bobtail Creek from the Seminary to Manard. So looking for such road on the Topo map it appears to exist today and clearly shows up on the aerial photos but I cannot find a designator/name for it on line. This road proceeds due west from the Seminary wiggling its way north of Bobtail Creek past Jones Cemetery to Berch Hole where it turns south on a section line crosses Bayou Menard and runs just west of Woodall Springs and appears to run into the old 1902 RR roadbed which is not on the Topo map but clearly visible on the aerial photo and joins 62/10 just east of where 62 crosses Bayou Menard 5.8 miles east of Ft Gibson.

Map showing progress of allotment in Cherokee Nation / compiled and drawn by R.L. McAlpine in 1903 concurs with this north of Bobtail creek route and refers to the Cherokee Seminary as the Cherokee Insane Asylum. It also shows a community by the name of Eureka on this road which I've not located on current maps.
