Surname Saturday: Rineharts and Steiners and Larimers, Oh My!

These surnames from hubby's family tree will be my main focus during sessions at the NGS conference:

• Rinehart - Joseph W. Rinehart (hubby's 2d great-grand) was born in Pennsylvania in 1806, died in Nevada, Ohio in 1888. When did the Rinehart family get to America? Who were Joseph's parents? Sessions on Pennsylvania and possible German connections might help!
• Steiner - Jacob S. Steiner (another g-grand of hubby's) was born in Pennsylvania in 1802, died in Crawford County, Ohio, before 1860 (he's not in that census). Where/when did Steiners come from? Who were his parents? Elizabeth Rinehart married Edward George Steiner in 1851 in Crawford County, OH (see above).
• Larimer and O'Gallagher - Robert Larimer (hubby's 5th great-grand) was shipwrecked enroute from Northern Ireland to America. Was he part of a family of Scotch-Irish immigrants? What is the family connection between the Larimers, the Shorts, and the Works? They held an annual reunion for several years in Elkhart, Indiana, and intermarried. Robert Larimer married Mary Gallagher (or O'Gallagher) in Pennsylvania. Where were the O'Gallaghers from and when did they arrive?
• Smith - Brice Smith (hubby's 4th great-grand) was born in Cumberland Cty, PA, in 1756 and died in Fairfield Cty, OH, in 1828. He was the first Brice we know of in the family, but not the last. Supposedly his father Robert Smith was born in Limerick, and Robert married Janet "Jean" in 1751 in Limerick. What's their story--why and when did they come to America? Sessions on Irish genealogy may help me research the Smith family.
• Bentley and Morgan - Still looking for the origins of William Tyler Bentley, born about 1795 in upstate New York, and his wife Olivia Morgan, also from upstate NY. Were they originally from England? Session on UK research might help.
• McClure and McFall - Still trying to find siblings for Benjamin McClure, son of John McClure and Ann McFall, who married in Rockbridge cty, VA, in 1801. Sessions on Scotch-Irish immigration will help me trace these families from Pennsylvania to Virginia and especially beyond.
