Genealogy is my hobby but I've taken it well beyond that. I went thru the learning curve about 10 years ago. I've made discoveries that my family never knew about. Like William Clark of the Lewis & Clark Expedition and I are 1st cousins, 6 generations removed. I have a half dozen 5X or 6X great-grandfathers that were Revolutionary War veterans. My 2X great-grandfather, William Wesley Crimm, along with his 4 brothers served in the Alabama 44th Infantry Regiment during the Civil War. They became a legendary unit. There was a book written about the 44th called Devil's Den. They took Devil's Den at Gettysburg. They were the only Confederate unit to capture Union artillery pieces at Gettysburg. The stats on my Crimm ancestors in the Civil War were pretty bad. 17 served in the Confederacy. 10 died in the War. 2 disabled. Pretty high casualty rate.
Some of the things I've learned in genealogy.
If you have English blood then all genealogy trails lead back to Virginia in the 1600's. There were two migration routes out of Virginia in the 1700's. West to Kentucky and surrounding region. Or south to the Carolinas and Georgia. In the 1800's the migration route was from the Carolinas and Georgia west to the Mississippi Territory and further west. Most Mississippians today trace their ancestry back to Virginia, the Carolinas and Georgia in the 1700's.
More Americans have German surnames than any other ethnic group. This was caused by 100K Germans/German speaking Swiss coming to the colonies in the early to mid 1700's to settle the interior of the colonies and another wave of 1.5 million Germans coming to America in the mid 1800's.
