I have found this info out about the Hallowell's I am researching. William Hallowell d. 1849 (he was living in Moreland Twp., Montgomery Co., PA when he died) he married Margaret Unknown, they had Sophia b. 1829 d. 1915, Sarah b. abt. 1835, Maria (may have gone by Mary) b. abt. 1838?, Joseph b. abt. 1823?, William b. abt. 1832?, Tamyson b. btwn 1832-1836, Samuel b. aft. 1840?, and Howard b. abt. 1845. I am not positive about the dates with the question marks. Sophia married Alfred Greaves son of George and Sarah Greaves bf. 1849, they had Anna Elizabeth, Tamyson H., Ella H., George H.(this is my husband's great great grandfather), and Elwood. Sarah married Jeremiah Webster bf 1850, they had Grant, and Ida (these are the only children I know of). Tamyson may have married Daniel Murphy, they had Joseph H.(this is the only child I know of). I think Joseph married Hannah Unknown, they had Edwin S., Emma, Fannie, and Anna(these are the only children I know of). William may have married Elizabeth Unknown, they had Sarah, Mary, Lena, Charles(these are the only children I know of). I don't know for sure but myself and a couple other Hallowell researchers think this William who married Margaret might be the son of Amos Hallowell and Elizabeth Roberts. If anyone out there can help shed some light on any part of this family please let me know. Thank you!
