An English-Japanese dictionary I have says "to come/bring to taw" means "to come/bring to the starting point" (from a game of marbles). I've found some examples of the word (underlines mine), though I'm not certain about their meanings:

(1) Week ends meant work in the field, in the woods to get heating or cook wood for the house. Sometimes it was other things, but occasionally we had time to play. Marbles. We were not allowed to play "Keeps" with other children. At home we played "Rolley-holey." We would start at a line and shoot for the first hole, then the second, then the third, then the fourth that we called "purgatory." Then we went back to first. The first player around was the winner. One kept shooting until he hit every hole. If he missed a shot he had to yield to the other player. Dad often played with us. If one felt he could hit the other's marble with his marble he tried, and if he hit, the other had to go back to "taw"--the starting line. If you were underprivileged and did not play such a, the word "Taw" can be found in your dictionary. It was also the name of a favorite shooting marble.

(2) But these Northern agitators of Slavery were not satisfied with the proceedings of Congress on the subject. They, I suppose, intended to abolish it in the States first, and then march their forces to the Atlantic, and embark them on board of canoes, and take the vessels on the high seas engaged in the Slave Trade, and bring them to taw, too! These would-be-called philanthropists seemed to have forgotten the old maxim that, "if you wish to find the spring, go to the head of the branch;" for they could stop the boil, and then the strength of the current would be greatly mitigated.
--Berry Harrison, Slavery and Abolitionism (1861), p. 10.

(3) All agreed to this except one young man. He stood out. Then some one happened to get a hunch that he was the only unmarried man in the combination. It was plain that he had intentions on the widow and planned to copper the whole pile by a matrimonial coup. The rest of the gang made short work of him. They found out that he was engaged to a girl in his district. Then they called him into open meeting and gave him just a week in which to get out the invitations--told him that if he didn't make good at the altar on schedule time the young lady would get a round-robin, or something of that sort, giving him a character that would last the rest of his life.
He came to taw quick, but inferred that he should expect to be handsomely remembered by his friends on the happy occasion. And he was. He received enough pickle castors, web-footed cake forks, spoons and table ware to stock the best jewelry store the little town had ever seen--and he opened business right away after the honeymoon. The other fellows thought they had done something mighty slick.

(4) All other bills in proportion. I, the said Capt. Jim, do hereby further declare to those indebted to me for eating, sleeping, drinking, or upon contract of any kind whatsoever, that unless they come forward immediately and make settlement, Michael Scott was never in Scotland if I don't sent a constable after them to bring them to "taw." so look out for Conklin or Ward.
