Re: alexanders in Frederick County. Md.

I am hoping to prove some relationship between Alexander and Baltzell families in Frederick Co., MD late 1700's & 1810 and:
Jacob George Meddert/Maddert/ Madtert/Methoit, whose wife was surname Alex/Alexin.
Several marriages in the Frederick Lutheran church was actually performed in the home of the above Meddert (active in that church).
Alexander and the Baltzell/Bosel/Pretsel/Pietzel/Peitsel, etc. families in Frederick Co. MD.
Associated families include my John Lefever who married May 12, 1800 Catherine Martz/Mertz/Markle born 1777 in MD (married by Meddert in his home among friends).
Associated families include: Woodring/Wotring, Weller, Henry Jackson (daughter Mary Pope Jackson born app 1785). Henry lived near Charles Baltzell and Fulton families in year 1800, Emmitsburg area,
Also Nimrod Duvall b 1770's? & wife Rebecca Waters. Samuel Duvall involved in estate of Elias Lefever intestate 1803, near Graceham.
