1848 Logan OH marriage record (v.B, pg.77).. "license Oct. 18, 1848 - John Everingham & Lovina Eunangst married 22 Oct 1848 in Logan, Ohio. On the 22nd day of October 1848, I solemnized the marriage of Mr. John Everingham and Miss Lovina Eunangst.. I.W. Johnston, J.P."

John & Lavina living next to his probable parents;
1850 Jefferson Twp., Logan, Ohio .. enumerated October 8th, "#119 - William Everingham, 57, carpenter, b.NJ,.. Mary Everingham 60, b.NJ,... | #120 - John Everingham 22, farmer, b.OH,.. Levinia Everingham 20, b.OH,.. Mary A. 1, b.OH." .. also of interest, both families were enumerated on October 16th 1850 with slightly different ages.. "#332 William Everingham 53, b.NJ,.. Mary 62, b.NJ,... John 21, b.OH,.. Levinia 17, b.OH,.. Mary 1, b.OH" .. this gives alternate dates of birth of; John (b.1829), Levina (b.1833)... living next to John & William's families is probable relatives; Jacob & Rebecca Bushawn!

1860 CENSUS Jefferson twp, Logan County, OH .. "John Everingham 32, farmer,.. Lavina 30, b.PA,.. Mary 12,.. Michael 10,.. Jacob 8,.. Rebecca 5,.. Charles 4,.. Gates 2. " The last child is hard to read... it looks like "Gates" a male, age 2. All children born in Ohio.

Lavina died fairly young;
1865 New Salem Cemetery, New Jerusalem, Jefferson Twp., Logan, OH.. "Lavina Everingham d.22 Mar 1865, aged 34y, 9m, 6d." .. Mystery.. at this same cemetery is a William G. LaPorte (1863-1892), same name as a man who married a Rebecca A. Everingham in 1886. Rebecca was the name of the wife of this William, but other researchers say his wife's name was Rebecca Bishop.???

A John Everingham married in Logan County, OH the next year;
1866 Logan, OH marriage record Vol.C, pg.486... "John Everingham & Mary Ann Marmon married December 31, 1866 at Logan County, Ohio".. License #375 John Everingham & Mary Ann Marmon in each case, it is possible that the bride's maiden name could have been Marrow. "I certify that on the 31, day of December 1866, I solemnized the marriage of John Everingham to Mary Ann Marmon, signed, January 31, 1867., Logan County, Ohio"

Luther S. Evingham 7,.. Laura Marmon 11 (all born in Ohio)" notice Mary is no longer living with them.. She may have been married by 1870. In the 1870 census of VanBuren township, Dayton, Ohio, Southern Ohio Lunatic Asylum there was a Mary Everingham age 19, schoolgirl born in Ohio listed. or,.. Also 1870 At Harrison township in Logan county Ohio there was a Mary Everingham, age 21, servant with an infant "Lilla" or "Leila" Everingham age 10/12 living with John & Sarah NEER.

not sure this is the same John, but date of birth, place and possible new wife fit.
