The subject of the question is Ulysses Sherman Grant (14 February 1867 - 21 September 1932)
1. His middle name was Sherman
2. His father was Lewis A. Grant /wiki/Ulysses_Sherman_Grant
Note: The Wikipedia article on Ulysses Sherman Grant states that his mother was the daughter of President Franklin Pierce. This appears to be an error. All the sources I can find about President Pierce indicate that he only had three children, all of whom were sons, and none of them survived until 1867. However, it appears to be on solid ground in stating that Ulysses Sherman Grant's father was General Lewis Grant.
