Morgan Family Line
Did you know that the Family Group Records submitted during the "Four Generation" project are available online as scanned documents? They are not indexed, so it's a little tedious to find the document you want, but what a useful resource! The information is similar to that found in other user-submitted databases (i.e. buyer beware, or check all sources) but there might be family records preserved here and nowhere else.
This record shows Frances Springthorp listed as a sister of Adeline Springthorp. Some names are misspelled, so the information does need to be checked.
The Springthorpe records begin at #1108 in the "S — Sprick-Sprowell" collection and go through #1122. If there are any notes or sources listed on the back, they are included on the next entry:
