When I stop to think about "why" I am looking at the family tree, several thoughts come into my head. Being alone, and in a family that is quite small, I am searching for some relatives that, for the lack of a better choice of words, want to be relatives, for the time when my immediate family ... becomes smaller.
I also would like to understand how I got to where I am today - and in part - the answer to that extends back in time, even before I was here. After all, my place in the world was determined by where my folks were when they had me. So in part, to me, this means needing to understand why some my predecessors moved from where they were, to where they ended up.
Lastly, I'm helping my mom with her Daughters of the American Revolution application. In the process, I've been learning how to find things I never expected to find on-line.
My dad's family never moved once it came to the United States. They arrived in Philadelphia and in the seven intervening generations, never moved to a place further than fifty miles from the William Penn statue on City Hall.
My mom's family on the other hand...
One of the links to "where I've come from" is a tangled one.

Meet my great-grandmother "Maggie" and the "Reverend", shown here sitting on the running board of an old Ford four-door sedan somewhere in Texas.
Maggie, or more formally, Margaret Jane Shipman, came to Honey Grove, Fannin county, Texas with her parents, John Madison Shipman and Paratine Avary in the autumn of 1880. Her mother's parents and her younger brother Daniel Perry Shipman, also moved at that time, from Mount Pleasant, Wayne county, Tennessee. Maggie was but 11 years old.
Why did this family uproot from Tennessee-Alabama border and move to Texas? I've a couple theories and no answers. One thought is that they moved to escape the carpetbaggers that made life miserable for folks in those parts after the Civil War. Apparently, this family of rather poor dirt farmers without pre-war slaveholdings, had no part in the "Lost Cause of the Confederacy", and just wanted to be left alone. Several of Paratine's family were hung after the Civil War by northerners who simply didn't like them.
Another theory is that they moved to Texas to settle on one of the Texas Land Grants given to distant cousins, Edward and Moses Shipman. They apparently had some role in the Texas Revolution and were offered land in Fannin, Red River, and Bexar (San Antonio) counties. I've not had the time to sort this possibility out yet.
At any rate, Maggie married a mysterious William Deary in November of 1891. She quickly had a little girl named Grace, and in February 2, 1893, she has a little boy named George (soon to always be called Bubbie). She is left a widow by November 1893.

In the meantime, Reverend Joseph Black Bush has moved to Texas with his wife Mary and two girls, Lizzie and Virgie, from Fountain Run, Monroe county, Kentucky shortly after 1880. Again, the "in-law" parents also make the long move.
In 1883, the Reverend and Mary have a third girl, who they name Tommie, and Mary dies in 1890.
Why did they uproot from the third or fourth generation family home in Fountain Run, Kentucky and go to Texas? Again, I don't know. My great-grandfather was a fire and brimstone preacher in the very southern baptist, "Churches of Christ". One of the leading and founding members of that church was in Texas. Perhaps my great-grandfather was "given orders from the church" to go there. Subsequently, he served as a teacher and minister in Chickasaw and Choctaw Nations, Indian Territory. Maybe he was a "missionary" in a sense?
With five children between them from prior marriages, they soon have six more.

The first child the Reverend and Maggie Bush had, was my grandfather, shown here in his full "Masonic Lodge" regalia, in Boston, circa 1955.
