What is the relationship between Hong Yinglun and Hong Xiuquan?

Hong Yinglun may be the direct ancestor of Hong Xiuquan in the last five generations.

According to historical data and Hong Xiuquan's genealogy, during the Yongle reign of the Ming Emperor, in the fourth generation, a wife led by Hong Nianjiulang (the ancestor of the Hong family in Shikeng, Meixian District, Meizhou City) moved from Fengshun Buxin to Yangmei Town, Shikengbao, Chengxiang County, Guangdong Province (later Shikeng, Jiaying State) to settle down, and built the enclosed house "Meikui Land".

During the Kangxi period of the Qing Dynasty, Hong Xiuquan's great-grandfather moved with his father from Shikengbao, Jiaying Prefecture (now Shikengbao, Meixian County, Meizhou City) to Guanlubu Village, Huaxian County (now Huadu District) (another way of saying it is: first moved to Fuyuan Water Village, and then moved to Guanlubu Village, but there is no record of Fuyuan Water Village in the genealogy, only Guanlubu Village is recorded, as Hong Xiuquan said in the preface to The Portrait of Hong Yinglun and his wife)

Hong Xiuquan is the sixteenth grandson of Hong after he moved to Guangdong, that is, the sixth generation after he moved to Guanlubu Village in Hua County.
