A couple of things.I wrote:
"Mary Caroline (or Caroline Mary) both are used on official documents. B. Aug. 16, 1849 m. David McClement Rowe, d. 1903"
She did not marry David MacClement Rowe, she married Benjamin Norris Rowe, and David was their son.
Secondly, I just found this last night via Heritage Quest...
History of Vanderburgh County, Indiana : from the earliest times to the present, with biographical sketches, reminiscences, etc. Publisher:Brant & Fuller, Madison, Wis.
"The junior member of the firm of Ehrman & MacClement, boot and shoe dealers, David MacClement, was born in Philadelphia, Penn., December 29, 1845.His paternal grandfather Thomas MacClement, was a native of Galloway shire, Scotland, moved to County Down, Ireland, settled in Bangor, in that country, there married Sarah E. Jamieson, a native of that place, and raised a respectable family.His father's name was also Thomas, born at Bangor, in 1811.When twenty-two years of age, he came to America, and was for a time engaged as a merchant tailor in New York and Philadelphia.In the latter city, early in 1845, he married Catharine J.R. VanDerslice, and eight years
later, moved to Dayton, Ohio, having meanwhile lived one year at Reading, Penn.D. T. MacClement was educated in the public schools of Dayton, Ohio, and at Philadelphia, Penn.At twelve years of age he started out in life to
maintain himself, and for some time was employed in a wholesale book and stationery house in Dayton.When the war broke out he offered his services, and was accepted.His name was entered on the muster rolls of the First
Ohio Volunteer infantry, but being under lawful age, his father had him released.He enlisted again in the Ninety-third Ohio infantry with the same result.Being determined to enter the service he finally enlisted in the One Hundred and Thirty-first Ohio infantry, under the name of T. V. Clement, and served faithfully until August 1864, when honorably discharged.
"Returning to Dayton, he entered the employ of the Grover & Baker Sewing Machine company, where he continued as book-keeper until 1868, when forming a partnership with his brother-in-law, B.N. Rowe, he took the agency of Howe
Sewing Machine company at this place.He continued in this business until 1875.April 15th of this year he was married to Miss Annie E. Bennett, daughter of Bylers Bennett, and then occupied various positions as an
accountant and book-keeper until 1886..."
This is my line, Thomas' sister was Caroline Mary MacClement.
Thomas and Catharine had more children than I previously mentioned they were:
David Thomas MacClement
Sarah Elizabeth MacClement
Caroline Mary MacClement
William Henry MacClement
George Lowery MacClement
Emma Elizabeth MacClement (I assume the first died prior to the second's birth)
Ellen Jeanette MacClement
Samuel Hopper MacClement
