For a very long time had I nary a clue as to the maiden name of my third great-grandmother Mary Dilliplane. Even learning her first name was hindered by the fact that she presumably died before 1850 and so was never enumerated in the US Censuses by name. The only record of her first name that I have found is contained in the death record of her son Joshua (presumed brother of my ancestor William). This is also the only source cited in “The Delaplaines of America” by Marvin G. Delaplane – which also only provides her first name.
But now I have a working theory as to her maiden name and parents – a hypothesis. I think that there is a chance that she might be Mary Swavely, the daughter of Adam Jr. and Esther. So far, the facts I’ve found regarding Mary Swavely are consistent with what little is known about Mary Dilliplane. (For more details see my website [link].) I am hoping definitive proof – one way or the other – lies in the estate file of Adam Swavely Jr. He died in November of 1842 and the Berks County, PA Register of Wills online index shows that there is a 25 page estate file. My next step in this process is to check out that file.
