Was Harriet Tubman's mother mulatto?

Answer 1

No.
Harriet was the 11th child born to Benjamin Ross and Harriet Greene (slaves of Edward Brodas), her given name was Araminta and she was often called "Minty" as a child. But by the time she was an adult, she was calling herself Harriet.

Answer 2

Harriet Tubman was born Araminta, or “Minty,” Ross in early 1822 on the plantation of Anthony Thompson, south of Madison in Dorchester County, Maryland. She was the fifth of nine children of Ben and Rit Green Ross, both slaves. Her father Ben was a ship carpenter and supervised the cutting of timber on Thompson’s plantation, while her mother Rit probably worked in Thompson’s house or in the fields. Harriet, her brothers and sisters, and her mother, however, belonged to Thompson’s stepson, Edward Brodess. When Harriet was a small child Brodess took them to his own small farm miles away in Bucktown. Separated from Ben, Harriet and her family experienced intense hardship and loneliness.
