Where is your source for the name William Anderson Alder, and his place of birth in Lafayette, Indiana?? I have his name as Anderson Alder, born 10 Jul 1814 in Loudoun Co., VA.I also have his marriage to Rachel Kemp on 3 Oct 1839 in Belmont Co., OH.Since she was born in 1818, I find it hard to believe that their son Lewis Kemp Alder could have been born in 1827.I have his birth as 1847, so could this date have been misread from some early, hard-to-read handwriting?Here is the info I have on the children of Anderson and his 1st wife, Rachel (Kemp) Alder:
1)George Latimer; b. 24 Jun 1840 Belmont Co., OH; m. 15 Oct 1863 Brown Co., IN to Margery Lovina Mead; d.1912 IN.
2)Susanna; b. 24 Jun 1842 Belmont Co., OH; m. Timothy Obenchain; d. 4 Dec 1930.
3)William Washington; b. 8 Aug 1844 Belmont Co., OH; m. 8 Oct 1873 DeWitt Co., IL to Serena E. Blain; 1 Jan 1914 Lafayette, Tippecanoe, IN.
4)Lewis Kemp; b. 22 Feb 1847 Belmont Co., OH; d. Maxwell, IA.
I also have info on all 10 children of Anderson Alder and his 2nd wife, Marthe Ann (Hubbard) Alder.I am descended from their son Leonidas Silcott Alder.I have researched back to Anderson Alder's 2nd great-grandfather, George Alder, who died in Piscataway, Prince George, MD in 1737.
I would be delighted to correspond with others working these lines.
