I have been dealing with a tough research problem in Mississippi today. The husband came to Natchez, Mississippi between 1800 and 1810 but of course I've been asked to locate the parents of the wife. They married in 1810 and she was dead by 1820! They had two known children. Their son died at the Alamo and the name of his maternal grandfather, a Revolutionary War patriot who served at Valley Forge, is given in a short biographical sketch written about him.
So great! You have the name of her father, what's the big deal? Well it's a common name and who's to say that it's even accurate. I guess it's a starting point.
Let the hunt begin.
There were seven men of that name listed on the Muster Rolls for Valley Forge. I've already eliminated one. Six more to go!
Time to search Revolutionary War pension and service records. Wish me luck!!
