I think I have a bit of info on your Emma. I have a general dbase of VO's as I try to sort out my own line. Happy to share with you or anyone researching VO's and reading this...is in excel.
I have four Emma's; two of which I think are yours. I will combine data as I make an entry for each known fact. These two are probably the same person. (The other two entries were born 1848 and 1850.)
Emma F. VanOrder b: Jul 1858 in NY or VT. Father: Charles VO (1817-); Mother: Louisa (1826-). Husband: Charles T. Atwell. Had 11 children.
If you can find Kevin Horsch...this is his line. Found in census records 1860 also. Last email I had for Kevin was <email@example.com
