At 18 years of age, Maggie apparently was her own woman, as Isaac relates in the next journal passage.
Thursday, September 21, 1865 Went to Washington [county seat] to get married to Maggie Taylor did not marry her because she would not have me unless I would raise chin whiskers
Isaac and Maggie did get a marriage license that day. Maggie’s brother, David Taylor, declared that he was personally acquainted with both Isaac and Maggie and that Maggie was 18 years of age. 
Evidently, Isaac and Maggie came to terms because they were married later that day at the home of Capt. Wilson.  After what appears to be a bumpy courtship, Isaac and Maggie began their long, loving life together.

Isaac had a thirty-day furlough during late February 1864. He returned home for a much-needed visit. It may have been at this time that he became interested in Maggie Taylor, the younger sister of Isaac’s first wife, Elizabeth. Isaac’s journal entries started to periodically mention that he and Maggie corresponded. Once Isaac was mustered out of the Army and was home, it was clear that he was very interested in Maggie. However, their courtship would go through some rough patches — right up to the day they married.

Isaac harnessed his horse to his new wagon and set out for the Harvey Taylor residence on August 12, 1865, where he overnighted. The next day, he brought Maggie, Stephen, Allice, Amanda and Abigail out to his farm where they “had a gay time”.
Stephen and Allice were probably the children of Isaac Leighton, the farmer Isaac worked for when he was about 18 years of age. Amanda was Isaac’s sister who married Ezra Bradford. Abigail’s last name is not known.
