What is とう in 行きとうない


I tried researching it myself and came away with the possible meaning of ている
in dialect. Is that right? If it helps, this is the line I happened upon the
とう in question:

> 私はもう行きとうない




“行きとうない” is the same as “行きたくない” in the standard Japanese.  
“私はもう行きとうない” means that _I don’t want to go anymore_.
