As there is no information listed here on Regina's parents, I wish to help make the connection. Her mother was Elizabeth Moser (1845-1915), and her father was Peter Luginbuhl. Elizabeth was the sister of John Moser, Born in Wayne County, Ohio on August 2nd, 1828. John Moser was minister of one of the earliest Swiss churches in Putnam and Allen Counties. He was chosen by lot to lead, and was minister from 1853-1908. He was made Elder of the Swiss church from 1864-1903. He passed away on July 10th, 1908. There are considerable first-hand sources on John and Elizabeth Moser available in Bluffton, Ohio. Some of Elizabeth's letters to her brother John are quoted in the manual commemorating the 175th anniversary of the original Mennonite Church in the Swiss community of Bluffton. Elizabeth's husband, Peter Luginbuhl, is the son of John C. Lugenbuhl "Sager Hans" (10/4/1803-10/7/1873) and Anna Maria Thuler (Diller) (3/7/1798-5/26/1853). John C. was the son of Christian Luginbuhl (1779-9/17/1847) and Katharina Steiner (6/25/1781-2/21/1832) of Bluffton founder fame. Regina Luginbuhl was an only child to Elizabeth and Peter, perhaps because Peter had a previous wife (Marianna Amstutz) and so they may have been older parents unable to have other children.
Hi, Georgia ... Welcome to Geni!
If you accept the pending merge request (https://www.geni.com/merge/compare/6000000147805208967) for your father, then you will 'connected' to this branch of Geni's shared World Family Tree!
From your note in this public Discussion, I went to look at some of the potential matching records and found an existing profile for her father on Geni ... and added her mother (Elizabeth Moser) from the matching FamilySearch.org profile.
Once you are connected, you be able to add to and correct details on her parents -- and other family members as well. It looks like there are a lot of possible matching records for this family. (You might even find that you & I are not too distantly related via one marriage 'hop' <smile>.)
It'd be nice to have someone with some interest & 'expertise' to care for this branch of Geni's shared World Family Tree <smile>.
Oh ... FamilySearch.org does have two possible brothers for Regina (one apparently an infant death?), but there aren't currently any good records supporting them. (Links are in the profiles' About for Regina & her parents which point to the FamilySearch info.)
