Parenets of Sophus Neble were Martin and Karen (Poulsen) Neble.
Same parents for John Louis Neble - so they were brothers, per IGI.
per IGI, John Louis Neble was born 16 JAN 1861 in Stubbekjobing, , , Denmark, died 17 MAR 1926 Omaha, Douglas, Nebraska, buried 21 March.
Daughter to Sophus Neble, Frances, married Dr. Glen Miller in Omaha, per online biography of Sophus F. Neble. By the say Sophus senior was married twice.
Son Eywind Neble was born 10 Aug 1890 and died in Nebraska Mar 1965 (SSDI)
Sophus F. Neble traveled back to Denmark in 1895, with son Sophus, age 10; record on Ancestry.com
The son Sophus F. Neble (junior) born 08 October 1886 in Nebraska died in Los Angeles, California, 07 Aug 1970 per record on Ancestry.com
The whole family went to Denmark in 1906 (Sophus, Olivia, Sophus, Eywind, Frances). Per Ellis Island record:
http://www.ellisisland.org/shipping/FormatTripPass.asp?sship=United%20States&BN=P00227-8&lineshipid=925&shipid= In 1910 census in Omaha Sophus junior is married to Anna, age 19.
per social security death index (SSDI) an Anna Neble dies Beverly Hills, Los Angeles, California, 14 March 1993; she was born 5 Oct 1893.
In 1930 census in Omaha, Sophus (junior) and Anna have a daughter Dorothy age 19 (born about 1911).
Dorothy Neble born 28 Sep 1910 died 26 Apr 2007 in Los Angeles; her social security number was issued in Nebraska. So maybe Dorothy never married.
Per IGI a Hans Neble married Mathilde Johanne Rehne 09 FEB 1889 in Douglas County, Nebraska.
A U.S. passport application 10 Apr 1914 for Hans P. Neble says he's born in Stubbekobing, Denmark, 08 October 1863. Spouse Marie. In 1930 he was on a ship (the Amerika) that departed Copenhagen and arrived Los Angeles, California 12 September. He's with Marie, says he was naturalized in Omaha Nebraska 1891, and now lives at 522 Avondale Avenue, Brentwood Heights Station, Los Angeles.
In 1930 census in Omaha, Douglas, Nebraska Hans P. Neble has a daughter Maude A.
Maude Alice Neble born 12 Jun 1894 in Omaha and lives in Omaha 1914 applies for a passport 10 Apr 1914 - same as her dad.
I think the Nebles in Brooklyn, New York, are also a good bet as a lot of people from Stubbekobing area are there.
