They have built an online database around those names, and welcome input from people who may share a name that's in the database, or have such names as part of their family lore.
``The whole point of the project is to ask the African diaspora, people with any African background, to help us identify the names because the names are so ethno-linguistically specific, we can actually locate the region in Africa to which the individual belonged on the basis of the name,'' said David Eltis, an Emory University history professor who heads the database research team.
So far, two men named Obama sit among some 9,500 captured Africans whose names were written on line after line in the registries of obscure, 19th century slave trafficking courts. The courts processed the human chattel freed from ships that were intercepted and detoured to Havana, Cuba or Freetown, Sierra Leone. Most of the millions of Africans enslaved before 1807 were known only by numbers, said James Walvin, an expert on the trans-Atlantic slave trade. Once bought by slave owners, the Africans' names were lost. Africans captured by the Portuguese were baptized and given ``Christian'' names aboard the ships that were taking them into slavery.
But original African names _ surnames were uncommon for Africans in the 19th century _ are rich with information. Some reveal the day of the week an individual was born or whether that individual was the oldest, youngest or middle child or a twin. They can also reveal ethnic or linguistic groups.
The president's father was from Kenya, on the eastern coast of Africa, and Eltis said it was rare for captives to hail from areas far from the port where their ships set sail. The unidentified Obamas on the slave ships sailed from west Africa. Walvin, author of ``The Zong,'' a book about the slave trade, said there were Africans who had been brought great distances before they were forced onto ships.
``Often their enslavement had begun much earlier, deep in the African interior, most of them captured through acts of violence, warfare or kidnap, or for criminal activity ...'' Walvin said in his book, which chronicles the true story of a captain who ordered a third of the slaves aboard his ship thrown overboard due to a shortage of drinking water.
Obama's ancestors, a nomadic people known as the River Lake Nilotes, migrated from Bahr-el-Ghazal Province in Sudan toward Uganda and into Western Kenya, according to Sally Jacobs, author of ``The Other Barack'', a book about the president's father. They were part of several clans and subclans that eventually became the Luo people of Kenya, Jacobs writes.
The president's great-grandfather's name was Obama. Obama is derived from the word ``bam'', meaning crooked or indirect, she said in her book.
But it's also possible that Obama was a name used by other cultural groups in Africa and for whom the name had a different meaning.
The slaves found aboard intercepted ships provided their names, age and sometimes where they were from, through translators, to English and Spanish speaking court registrars who wrote their names as they sounded to them.
Body scars or identifying marks also were recorded. The details were logged in an attempt to prevent the Africans from being enslaved again, which didn't always work.
Emory's researchers are including audio clips of the names as they would likely be pronounced in Africa.
``These people enslaved were not just a nebulous group of people with no place and no name,'' said Kwesi DeGraft-Hanson, one of the researchers, who has found variations of his name, his brother's and his children's names in the database. He is originally from Ghana. ``That's how lot of us view slavery. We don't have names faces to go with it ... It makes them that much more removed from us.''
Eltis and his researchers acknowledge the database may not help African Americans with genealogical research because records on the Africans once they were freed from the ships are harder to find, if they exist at all.
However, the project provides another piece in a major jigsaw, and helps put together a bigger picture on slavery, Walvin said.
Before this project, Eltis and others assembled a database of 35,000 trans-Atlantic slave ship voyages responsible for the flow of more than 10 million Africans to the Americas.
Together, the two databases provide some details on the horrific voyages of the Africans, including the Obamas.
The Xerxes, which carried one of the unidentified Obamas, was a 138-foot (42-meter) schooner that began its voyage in Havana with a crew of 44. Five guns were mounted aboard when the ship left on a slave purchasing trip to Bonny on Feb. 10, 1828.
Sailing under the Spanish flag, the ship's captain Felipe Rebel purchased 429 slaves, nearly one third of them children, before setting out on a return trip to the Americas. But on June 26, 1828, the Xerxes was intercepted and forced to dock at an unknown Cuban port. By then, 26 slaves had died.
The other unidentified Obama, 6-foot-3-inches (1.9 meters) tall, was one of 562 Africans shackled in the belly of the Midas. The vessel was a Brig, a fast, maneuverable ship with two square-rigged masts. It was equipped with eight guns.
Midas' captain J. Martinez and a crew of 53 left Cuba on an unknown date. It left Bonny with 562 slaves but was intercepted. It docked in Cuba July 8, 1829 minus 162 slaves who had died during the voyage.
Some slaves freed from seized ships were returned to Africa, but not always to their original homelands. Some were sent to Liberia or were allowed to remain free in the cities where the courts were located. Some may have been re-enslaved and some died on ships that were returning them to Africa.

200년전 노예선에 '오바마'가 있었다
1828년 6월, 스페인 국기를 단 악명 높은 노예무역선 크세르크 세스(Xerxes)호에는 '오바마'라는 이름의 노예가 타고 있었다.
이듬해 7월 노예선 미다스(Midas)호에도 또 다른 오바마가 등장한다.
미국 최초 아프리카계 대통령인 버락 오바마와 이들은 과연 연결돼 있을까.
AP통신은 30일 오바마 대통령과 노예선의 오바마 사이에 이름 외에 어떤 다른 공통점을 보여주는 증거는 없다고 역사 전문가들을 인용해 보도했다.
에모리대학의 데이비드 엘티스 교수(역사학)가 이끄는 연구진은 19세기 법정 기 록에서 취합한 약 9천500명의 노예 이름으로 데이터베이스를 구축했다.
아프리카 고유 이름은 출신 부족, 언어, 출생 일시, 형제•자매 중 태어난 순서 등 개인 정보를 내포하는 경우가 많다.
연구진이 데이터베이스를 충실히 확보한다면 아프리카계 후손은 조상의 이름을 통해 자신의 기원을 알아낼 수도 있다는 뜻이다.
연구진이 현재까지 구축한 데이터베이스에는 오바마라는 이름이 두 번 나온다.
하지만 노예선에 붙잡힌 아프리카인들은 항구 근처 서아프리카 출신이 대부분이고 내륙 깊은 곳에서 온 경우는 드물다.
오바마 대통령의 아버지는 노예무역 항구에서 먼 아프리카 동부 케냐 출신이다.
따라서 지금까지 구축된 데이터베이스만으로는 대통령 오바마와 노예 오바마를 연결지을 끈을 찾기 어렵다.
그러나 때때로 내륙 지역에서도 노예 '포획'이 이뤄지기도 했다는 게 전문가들 의 설명이다.
오바마 대통령의 아버지는 아프리카 루오(Luo)족 계열 부족 출신으로, 이들은 과거 수단에서 우간다를 거쳐 케냐 서부로 이주했다.
샐리 제이콥스가 쓴 '또 하나의 버락'에 따르면 오바마라는 이름은 '구부러진' 또는 '둘러가는'이라는 뜻의 부족어 '밤(bam)'에서 유래했다.
