I am searching for info on Lantis family. My father was Warren Pratt (never knew him, deceased when I found him); grandmother - Violet Lantis; Great Grandfather - Frank Lantis; Great-great-great grandfather - Levi Lantis; great-great-great-great grandfather Ezra. To date, I believe I have the correct information, however, my understanding is that Frank is Indian and was raised on a reservation, however, I cannot seem to find this particular information.

The family comes from Kansas/Ohio/Missouri. They have been part of the "four tribes."

Can anybody help?

Most likley he was part of the Moravian missionaries living
on the reservation.

Landes (Landis, Lantes, Lantis) Family. The family traces its ancestors back to Hirzel, near Zurich, Switzerland to the 16th century to Johannes Landes and his wife Katharina Schinz. Hans Landes, their son, was beheaded in Zurich in 1614 for *anabaptist beliefs. Many Brethren families also stem from another son, Rudolph (b. 1547), whose descendant *Johann Heinrich Landes (1683-1726) and his wife Elizabeth Hirt Landes arrived in Pennsylvania from the Alsace and settled on the Schuylkill River before 1723. On Christmas Day of that year they became Brethren through baptism at Germantown by *Peter Becker. Landes fathered three daughters and a son, *Heinrich Hirt Landes (1716-1809), who married Elizabeth Naas, daughter of *Johannes Naas. Heinrich's second marriage was to Catherine Graff.

Henry Naas Landis, Jr. (1740-1825, m. Mary Carver, Elizabeth Fishbourn) moved to Franklin co., VA, ca. 1790. Their neighbors were the families of elders Peter Eichenberg and Jacob Miller. These three patriarchs moved to the Ohio frontier with married children in the early 1800s. Michael Landis moved to Montgomery Co., OH, from Swatara, PA, ca. 1828. He was elder at Wolf Creek until he led the *Landisites away from the church. The Landises have been very active in southern Ohio. The organizational meeting for the Old German Baptist Brethren was held Nov. 25, 1881, at Abraham Landis'home in the Salem district.
Westward settlement of the family has included Indiana, Illinois, North Dakota, Kansas, Oklahoma, and California.

I have a letter written by Joyce Pap on April 1986, after visiting her 5th Great grandfather Henry Landis gravesite here in Preble county Ohio. From what I gather, this Henry is the son of Henry Landis b.1740 Amwell twp Rengoes, Hunterdon co. N.J. and Elizabeth (Naas)1716-1809. If you happen to read this Joyce, contact me, nothing important.
