Hi,
Aoe Tsunetsugu was a goban kaji, he worked around Jôgen (1207)
According Fujishiro, Naotsugu works exist from Karyaku, Gentoku, Kenmu, Kôei and Kan'ô.
Same thing on others sources. Tsunetsugu = Ko-Aoe, Naotsugu= Chu-Aoe.
Edit,
After further research it seems there are two Tsunetsugu, Toko taikan listed one in Jôgen (1207) and one in tenpuku (1233).
