I know this is a bit of a strange question but the thought just popped into my head.
My class just watched a documentary on interviews with former slaves. I remembered one woman talking about being selected to have children with a male slave on the plantation. After a little searching I found that nationalhumanitiescenter.org has excerpts from these interviews. Here's the one with the aforementioned woman: "Dere am one thing Massa Hawkins does to me what I can’t shunt from my mind. I knows he don’t do it for meanness, but I allus [always] holds it ’gainst him. What he done am force me to live with dat nigger, Rufus, ’gainst my wants. After I been at he place ’bout a year, de massa come to me and say, “You gwine live with Rufus in dat cabin over yonder. Go fix it for livin’.” I’s ’bout sixteen year old and has no larnin’, and I’s jus’ igno’mus chile. I’s thought dat him mean for me to tend de cabin for Rufus and some other niggers. Well, dat am start de pestigation for me. I’s took charge of de cabin after work am done and fixes supper. Now, I don’t like dat Rufus, ’cause he a bully. He am big and ’cause he so, he think everybody do what him say. We’uns has supper, den I goes here and dere talkin’, till I’s ready for sleep and den I gits in de bunk. After I’s in, dat nigger come and crawl in de bunk with me ’fore I knows it. I says, “What you means, you fool nigger!” He say for me to hush de mouth. “Dis em my bunk, too,” he say. “You’s teched in de head. Git out,” I’s told him, and I puts de feet ’gainst him and give him a shove and out he go on de floor ’fore he know what I’s doin’. Dat nigger jump up and he mad. He look like de wild boar. He starts for de bunk and I jumps quick for de poker. It am ’bout three foot long and when he comes at me I lets him have it over de head. Did dat nigger stop in he tracks! I’s say he did. He looks at me steady for a minute and you’s could tell he thinkin’ hard. Den he go and set on de bench and say, “Jus wait. You thinks it am smart, but you’s am foolish in de head. Dey’s gwine larn you somethin.’ “Hush yous big mouth and stay ’way from dis nigger, dat all I wants,” I say, and jus’ sets and hold dat poker in de hand. He jus’ sets, lookin’ like de bull. Dere we’uns sets and sets for ’bout an hour and den he go out and I bars de door. De nex’ day I goes to de missy [mistress: master’s wife] and tells her what Rufus wants and missy say dat am de massa’s wishes. She say, “Yous am de portly gal and Rufus am de portly man. De massa wants you-uns for to bring forth portly chillen. I’s thinkin’ ’bout what de missy say, but say to myse’f, “I’s not gwine live with dat Rufus.” Dat night when him come in de cabin, I grabs de poker and sits on de bench and says, “Git ’way from me, nigger, ’fore I busts yous brains out and stomp on dem.” He say nothin’ and git out. De nex’ day de massa call me and tell me, “Woman, I’s pay big money for you and I’s done dat for de cause I wants yous to raise me chillens. I’s put yous to live with Rufus for dat purpose. Now, if you doesn’t want whippin’ at de stake, yous do what I wants.” I thinks ’bout massa buyin’ me offen de [auction] block and savin’ me from bein’ sep’rated from my folks and ’bout bein’ whipped at de stake. Dere it am. What am I’s to do? So I ’cides to do as de massa wish and so I yields. . . . I never marries, ’cause one ’sperience am ’nough for dis nigger. After what I does for de massa, I’s never wants no truck with any man. De Lawd forgive dis cullud woman, but he have to ’scuse me and look for some others for to ’plenish de earth."
