Among the two provinces, there are the following counties with the word Ling:
Jiangling county and Yiling District in Jingzhou District, Hubei Province
Liling County and Chaling District in Changsha, Hunan Province
Lingling County, Yongzhou District, Hunan Province
Baling County, Yuezhou District, Hunan Province
Wuling County, Changde District, Hunan Province
Yuanling County, Chenzhou City, Hunan Province
The reason why the states are listed is because some old people are not clear about the administrative establishment at that time, and it is easy to call "Chaling State" Chaling County for short, and this is also the case.
In this way, even if you only start from Lingxian County in Huguang Province mentioned in your question, there are at least eight eligible counties to check, which is too much trouble. It's not that the pursuit is hopeless, but that it takes too much effort.
Therefore, I suggest that you concretize your own family information first, otherwise, it would be too much trouble to trace Qidu Village only according to such a sentence in Lingxian County, Huguang Province during the Kangxi period.
The so-called concreteness means that you can provide more relevant clues. According to your family legends, genealogy and inscriptions, you can locate the place you are looking for between Huguang Province and a Lingxian County, or between a Lingxian County and Qidu Village, plus certain geographical restrictions.
Let me give you an example:
The Deng family in Dengjiawan, Yuanjiang, was born in Jing, and its tenth Sun Dexiang, whose name is Qichang, moved from Taihe County, Ji 'an, Jiangxi Province to Dengjiawan (a Dengjiashan) in Wayao Lake, Qidu, Yuanjiang, Hunan Province in the first year of Ming Dynasty. Later generations lived in Dengjiawan, Hanshou Niubitan and other places. The ancestral temple is in Dengjiawan.
The preface of the class preaches the truth, celebrates the beauty of jade burning, inherits the world with poetry and calligraphy, has a developed family voice, is famous for the country, and is loyal and sincere.
The above is the genealogy of the Deng family. You can notice that their home once appeared near Yuanjiang [probably in Yuanling County, Hunan Province]. But here, Qidu should not be a village, but a place name at the township level today. There are certain conditions to look for these things today, but the premise is to have a basic orientation. It will take too much energy not to look for all the eight counties I mentioned above.
If you really have no more information to add, then at least tell me what surname you are looking for, such as Huang, Peng, Luo, Tan, Mao, Gong, Deng, Jiao, Fan, Sheng, Yan, Tang, Dai and so on. I'm helping you find the origin of this surname in Hunan and Guangdong provinces, which may be helpful to you.
