As the sisters grew up, they more and more showed their dislike of slavery and their disposition to aid such colored people as were within their circle. Such conduct could not escape observation, and the result was their banishment from their Southern home. They were given the alternative of "behaving themselves" or going North to live. They were not long in deciding, and they became residents of Philadelphia. Here they joined the Quakers, because of their coincidence of views on the slavery question. They had before been Presbyterians, having been raised as such. They became industrious and noted Anti-Slavery lecturers. To one of them is to be credited a notable oratorical achievement. Being no longer able to ignore the growing Anti-Slavery sentiment of its constituency, the Massachusetts Legislature in 1838 appointed a committee to consider the part that that State had in the subject of slavery, and especially in connection with slavery in the District of Columbia. The committee asked an expression of their views from those entertaining different sentiments on the subject. The Anti-Slavery people invited Angelina Grimké to represent them. The sessions of the committee were to be held in the great hall of the Legislature in the State House, where, up to that time, no woman had ever spoken. The chairman of the committee, however, consented that Miss Grimké should be heard, and the fact that she was a woman probably helped to bring out an immense audience. She spoke for two hours, and then, being asked to speak again, at the next meeting, she spoke for two hours more. The impression she produced may be inferred from the fact that the chairman of the committee was in tears nearly the whole time she was speaking. The effect upon all who heard her was admitted to be very great. The sincerity of these women was put to an unusual test. They had a brother who remained in South Carolina, where he was a prominent citizen and a large slave-owner. Like many sharing the privileges of "the institution," he led a double life. He was married to a white woman by whom he had children. He also had a family by a colored woman who was one of his slaves. In his will he bequeathed his slave family to a son by his lawful wife, with the stipulation that they should not be sold or unkindly treated. Of these things the Grimké sisters knew nothing until after the war which had freed their illegitimate relatives. Then all the facts came to their knowledge. What should they do about it? was the question that immediately confronted them. Should they--"Carolina's high-souled daughters," as Whittier describes them, and not without some part in the pride of the family to which they belonged--acknowledge such a disreputable relationship? Not a day nor an hour did they hesitate. They sent for their unfortunate kinspeople, accepted them as blood connections, and took upon themselves the duty of promoting their interests as far as it was in their power to do so.
