I'm not sure I understand what you're saying here.
Truth is, I'm not researching the Burgwins, I'm researching the ORMSBYs.On a lark, I tossed out some information that I came across on related families where the information was good and the families removed a generation or two, maybe not knowing to look where I found it... which is to say, not realizing the line crossed the Ormsbys and there was tons of published information on the Ormsbys that MENTIONED their family.
I just did it out of good genealogy citizenship, ha ha!
The Ormsbys are a very prominent family in the history of Pittsburgh, and there's a lot of documentation about them.
What follows is from "A short account of the Family of Ormsby of Pittsburgh" by Oliver Ormsby Page pub 1892, p 28-30.
The Starting with where the line I'm researching - Ormsby crosses Phillips before crossing Burgwhin - crosses Burgwin (and then I'll backtrack):

I know it seems long, but this is a link directly to the book I'm referencing: http://digital.library.pitt.edu/cgi-bin/t/text/pageviewer-idx?c=pitttext;cc=pitttext;sid=b4dc3c9a11a09445539aba0e615a6c3a;q1=Oliver%20Ormsby;op2=And;op3=And;rgn=full%20text;idno=00add0854m;view=image;seq=0003http://digital.library.pitt.edu/cgi-bin/t/text/pageviewer-idx?c=pitttext;cc=pitttext;sid=b4dc3c9a11a09445539aba0e615a6c3a;q1=Oliver%20Ormsby;op2=And;op3=And;rgn=full%20text;idno=00add0854m;view=image;seq=0003
You can search the University of Pittsburgh digital library at http://digital.library.pitt.eduhttp://digital.library.pitt.edu.There are 46 different books that refer to Oliver Ormsby in their collection, I'm sure that at least some portion of those will refer to this Burgwin line as well.
