Tombstone has "HATTIE", not Henrietta. She never went by her real given name.

Hattie and her husband Chester bought 380 acres containing the original Knob Creek farm on August 26, 1931 from John W. Crady, along with Crady’s adjacent 62.5 acre tract. Chester Howard came from an established family that had founded Howardstown in 1833 and started a successful distillery supply store, the income from which provided the funds for the Knob Creek farm purchase. In 1931 they dismantled a single-pen log cabin thought to date from the early 1800s from the Gollaher farm, which was included in the land purchase. With the logs they constructed a cabin said to resemble Lincoln’s. Their neighbor Robert Thompson, who said that he remembered the Lincoln family’s cabin, assisted the Howards in the construction.

Howards purchased Knob Creek Farm with the intention of creating another memorial to Lincoln. This land was the Lincoln family’s home from 1811 to 1816, and by Lincoln’s own admission was the site of some of his earliest memories. Here, the Howards used the logs of a cabin belonging to the family of Lincoln’s childhood friend Austin Gollaher to re-build a hewn-log cabin said to resemble Lincoln’s boyhood home. Then in 1933, they followed in the established theme of Lincoln’s rustic log structure and built the adjacent Lincoln Tavern. This second structure, made of exposed round logs purportedly cut from trees felled on the site, was a popular dancehall and nightclub for travelers. After the sale of alcohol became illegal, the tavern was converted to restaurant and gift shop in the 1950s. In recognition of their significant role in Larue County tourism the site containing the cabin and tavern was listed in the National Register of Historic Places in 1988 as the Lincoln Boyhood Home. The National Park Service acquired the site from members of the Howard family in 2001 for inclusion in the Abraham Lincoln Birthplace National Historic Site.

Hattie was the first female to not ride a horse sidesaddle at the Larue County Fair, where it caused quite an uproar. She sewed her skirt up the middle and rode the horse like a man.

She did not attend the weddings of any of her children.
