Wikipedia shows that went comes from wendan, while go and gone are based on gon. They became synonyms in the 15th century and merged:
Development of a new preterite
In Middle English, ēode evolved into ȝede, yede, and yode. By the 15th century in southern England, wende (wend) had become synonymous with go, but its infinitive and present tense forms had ceased to be in frequent use. This was also true of the various ēode-derived preterites of go, thus a variant preterite of wend absorbed the function. After went became established as the preterite of go, wend took on a new preterite, wended. In Scotland and northern England, yede was gaed, regularly formed by suffixing -ed to a variant of go. Due to the influence of the region, southern English forms constitute the standard language of England, and so went is the standard English preterite. Spencer used yede to mean go with yode as its preterite form but as dialect.
