Thank you for your help. The answer is : anything and everything before 1800. Below is the earliest I have of my great grandfather, George. Who are William and Mary Jackson, for example?
[WORD doesn't transfer well.]
The first evidence of this family is in Nottinghamshire, Lenton, Bestwood Parish are William and Mary Jackson. They were the parents had William baptized at St. Firmin Church, Thurlby. Son William spent his life in agricultural labor, tethered to Lenton for half a century. Married to Sarah Hall, the couple raised eleven children, all baptized at Arnold St. Mary in Lenton (Rtc: parish records). One parent in this marriage, I suspect, had an ancestor carrying Mongolian blood between 1660-1690. In Europe, “Mongolian” after the 1200s means a tribal infusion such as Turkic, Tartar, Uralic, etc., completed in eastern and central Europe (DNA: 23andme; Wikipedia).
