I am descended from Solomon Keagle (b. Sept 15, 1821 in Penn - d, Mar 05, 1900 in Calhoun Co, Mich) and Rosanna Stroh (b. May 01, 1830 in Penn - d. May 14, 1912 in Calhoun Co, Mich). They were married Sept 27, 1849 (place unk).
They had 14 children:
Bagalia B. Keagle - Feb 17, 1851 - Indiana
Oliver P. Keagle - Sept 03, 1852 - Indiana
Charles W. Keagle - June 10, 1854 - Indiana
Solomon D. Keagle - Dec 23, 1855 - Indiana
Frank Keagle - Oct 24, 1857 - Indiana
Mary E. Keagle - Aug 29, 1859 - Indiana
Henry H. Keagle - Jun 26, 1861 - Indiana
John M. Keagle - Apr 14, 1863 - Indiana
Adam Keagle - May 24, 1865 - Ind
Sarah J. Keagle - Mar 20, 1867 - Mich
Matilda A. Keagle - Mar 20, 1869 - Mich
Leonard Keagle - Sept 28, 1870 - Mich
Clara Belle Keagle - July 18, 1872 - Belevue, Mich
--- married Issac W. Strong Dec 11, 1895 -- Tekonsha, Mich
---- died Nov 20, 1953 -- Burlington, Mich
George Keagle - Sept 27, 1874 - Mich
Although some birth dates don't make sense as you count months between children, they are directly out of Clara's Bible which is in my possession. Likewise the locations noted above. I also have an old tin photo of Solomon and Rosanna from sometime around the 1860's and shows them in attire typical of what might be called Protestant Brethern. I do know that Issac and Clara (my GG-parents) met at a UEB icecream social in Burlington, which might track with the earlier attire in the photo.
I have had no luck tracking down the Keagle or Stroh lines in Pennsylvania.
