On Page 62 the "Memorial of the Baxter Family" geneology book (available in imaged format on Google books), there is a reference to a Harriet Baxter who married a William Warren House in Pittsburgh in 1818. William Warren House fathered William Henry Baxter House in 1820 and from whom I decend. William Warren House remarried after 1820 and fathered a second son (Samuel House)and half brother to William Henry Baxter House. The references I have mention that William Warren House's mother was a sister to the famous Revolutionary War General Joseph Warren of the Bunker Hill battle, but I don't find any confimration that Gen Warren had sisters. So, I've hit a wall in trying to tie William Warren House to any of the other established House geneologies. Can anyone help?
