Lundy- You and I are cousins! Rev. Archibald MCROBERT is my 5th great-grandfather. My great-grandmother was a BAKER in this line and I have never heard of a half sibling either. My grandmother (whose mother was the Baker) continued her father's genealogy work (he was a professional genealogist). I have all of the paperwork done of this line and it does not show a half sibling.
On a side note, Rev. Archibald MCROBERT is a recognized Patriot with the DAR. The only women who have joined under him, to date, are descendants of William (Will)E. PARHAM (my great-grandfather). The DAR has him erroneously recorded as "McRoberts"
To fill in some of the blanks you have:
Susan John HARTMAN was born 1834, Virginia, died 1907. Sources include "Bakers in Midway" pg. 13, 14, 18; 1870 U.S. census, Ohio; and records from my grandmother who notes "The record says, 'Wm. Munford Baker, b. 1825 married his cousin, dau. of John Hartman and Susan G. McRobert by name of Susan G. Hartman.' "
The Susan G. MCROBERT noted above is the daughter of Theodorick Bland MCROBERT and Agnes Woodson MORTON.
I have what I refer to as the "Baker" document written 19 Dec 1936 by Will E. PARHAM. In it he writes, "There were several children born to Wm. Munford Baker and wife, though only one living is Daniel Baker Baker." You have a question mark for th date of death for William Munford Baker, Jr. Based upon Will E. PARHAM's document, he was deceased prior to 19 Dec 1936. Also, you have a birth year of 1862 for William Munford Baker, Jr. According to the book, "Bakers of Midway" (I forgot to note the page) he was born 19 Sep 1864.
I have two Joseph BAKER's in my database. One is Joseph Black BAKER b. 4 Apr 1869 who married Mary HARPER. He is the son of William Hartman BAKER. William is the son of Rev. William Munford BAKER, Sr. So this Joseph BAKER is the great-grandson of Rev. Daniel S. BAKER D.D. (1791-1857).
The other Joseph BAKER was born in 1762 and is the son of Benjamin BAKER, Sr. (1722-1785) and Elizabeth LAX.
Daniel Baker BAKER (1855-1937) who married Elizabeth GOWDY was William Munford BAKER, Jr.'s brother. They were also second cousins via the Theodorick Bland MCROBERT and Agnes Woodson MORTON lineage.
Rev. Daniel S. BAKER D.D. and Elizabeth Venable MCROBERT had four sons and three daughters (I have exact dates if you want them):
(1)Howard Melancton BAKER, Esq. (1817-1890)
(2)Theodora Louis BAKER (1818-1885) m. 1st Mr. SCOTT; m. 2nd, 7 Dec 1856 Henry S. HUGHES
(3)Daniel Speece BAKER (10 Dec 1820-19 Aug 1821)
(4)Rev. Daniel Sumner BAKER (1823-1900)
(5)Rev. William Munford BAKER, Sr. ((1825-1883)
(6)Daughter BAKER (Mar 1827-Mar 1827)
(7)Agnes Elizabeth BAKER (1829-1840)
Daniel Baker BAKER, who married Elizabeth GOWDY, was the son of Rev. William Munford BAKER, SR. not Rev. Daniel Sumner BAKER's son.
You are correct that Daniel Baker BAKER and his wife, Elizabeth GOWDY, had a son named William Munford BAKER. He was born in 1890, though, not 1900. Here is the information from his birth certificate:
