Margaret (Killian) Price migrated from Germany to Philadelphia.
Margaret Killian was born in Ansbach, Bayern in 1726, the daughter of Andreas Killian (1702 - 1788). She was christened in Saint Gallus Church, Erzberg, Ansbach, Bayern on 29 April 1726.  Margaret and husband, Michael Price are both mentioned her father's will.
The Killians arrived in Philadelphia on the British ship Adventure, on 23 September 1732. Margaret would have been eleven years old.
Margaret married Johannes Michael Price. Proof of this marraige has yet to be found in the form of a marriage bond. However, the primary authorities on these two families have offered the following:
Christine L. Neuenschwander, Price family historian writes:
Johann Michael Preisch was baptized in a Roman Catholic Church in Offenbach, Germany 9 Oct 1718 and died in Montgomery County, Virginia, United States between July and Oct 1802. His wife was named Margaretha but there is a question about her first name. For a long time it was believed that she was Margaretha Harless, sister of Philip, and is so listed by Harvey Lee Price. Mrs.Neuenschwander doubts this conclusion since she was unable to find a single vital record to support it. She did find record of a Margaretha Harless of Mulhofen (Muhlhoffen) German marrying Johannes Ruppel 19 Aug 1738 and supposes that she was Philip's sister. She thinks, on the other hand, that it is likely that Michael Preisch's wife was Margaretha Killian, born 1721 in the Rheinland Pfalz, Germany, daughter of Andreas Killian who emigrated to Philadelphia 23 Sept 1732. She bases this conclusion on the following item in Andreas Killian's will, written 22 Sept 1785, pro 1788: "I give to my son-in-law Michael Price, the husband of my daughter Margaret, on shilling sterling." 
This resulted in a joint memeorial marker for Mararet Price with the following dedication:
Because it is the belief of the Andreas Killian Descendants Historical Association that the wife of John Michael Price is the eldest daughter of Andreas Killian, the Association voted to join with the Price Society to erect a monument at the presumed burial site in the Wall Family cemetery in Price’s Fork, Virginia....
Margaret and John Michael had the following children:
David Price Sr.,
Alexander Price Sr.,
Michael Price II,
Margaret (Price) Lucas,
John Henry Price and
Jacob Price Sr.
Margaret's father, Andreas Killian, and all of their family settled in North Carolina around 1747. 
Margaret died in 1802 and was buried at Wall Cemetery Montgomery, Virginia in the Wall Family Cemetery, Montgomery County, Virginia, USA.
Michael Price was a colorful character. He and his siblings settled near what is today, Blacksburg, VA. In 1755 during the French and Indian war, Michael's brothers retreated north to the greater German settlement in the Shenandoah Valley. Michael was undeterred by Indian threat. He bought some of his brother's neighboring land and he and Margaret stayed. Family history tells of an occasion when Michael was reading his bible when Margaret saw through the window, an Indian, on their porch. The Brave lunged at Michael where the tomahawk landed in his raised Bible. This Bible, with the tomahawk cut was in the family until 1900 when it was lost in a house fire.
Jimmie was so gracious to Dan, Joe and me. We spent some time in the county courthouse admiring Michael's and Margaret's signature on land deeds and wills, very exciting indeed. Our tour started at the church where Michael and Margaret attended. Not far from this church in a pasture, is where Michael and Margaret are buried. Margaret has no headstone, which, without doubt, must be remedied. From there, you could see across the valley what was once Price land. In the distance, you can see Price's Mountain. Even in the grey of winter, it was a beautiful sight. Jimmie then took us to where Michael and Margaret lived in a stone 'fort'. The spring from where Margaret drew water is still there. The Fort is gone but some of the handcut stones are still there.
Michael had many skills, one of which was stone masonry. They had 2 homesteads, one in Tom's Creek and one in Price's Fork,
close by today's standards. Jimmie took us to a cliff overlooking the Horseshoe bend of the New River, to get a birdseye view of
some of the most disputed and fertile land. It was quite awe inspiring. It was a great trip. I must say that Jimmie is a special person.
He is a minister with a wonderful, caring, giving... 
Margaret was named in her husband's will. John Michael Price, Sr. wrote his will in 1802. It was probated in 1803 in Montgomery County, Virginia.

It may be possible to confirm family relationships with Margaret by comparing test results with other carriers of her mitochondrial DNA.
However, there are no known mtDNA test-takers in her direct maternal line.
It is likely that these autosomal DNA test-takers will share DNA with Margaret:
My only contention is that the will written in NC and Michael Price is in VA..where is the connection. Michael Price was a common name in both states at that time..most were English. If we tie in the NC Killians with the Virginia family of Price , that would be great. but a will stating a name mean very little without the tie in, I welcome everyone trying to clear this up. The Association has not released any docs but the will of Andreas Killian to my knowledge. I am aware that because of this Price Killian connection that the Price Society had a rift with many of the kin, when they just wanted some kind of proof.. and I think it continues to this day. I just want to have documents that Margaret Killian being in the Virginia New River Settlement As far as I know Price was not in NC
Could you please delete the notes under sources and look at the bio to see if you can organize it better. Maybe the section about their marriage should be in a box labeled resolved dispute or something with the will image within.
I think we need to make it look finished as the last time the entire bio seemed to collect forum style comments.
Also, Michael Price's story is a good one and his bio is also a mess. Let's do that one up as well once we have gotten to that point. He was a real pioneer
Would you like Michael Preisch/Price's will and if I can find it his immigration. The whole point is to prove our wikiTree profiles not a point, I would have been happy to help redo the line to what records say.
