5.  Email from "TnT":

I have discovered a specific death date for Nicholas Corbin of Baltimore Co. He was buried on Dec. 31, 1696 at St. Paul's Parish.  This is mentioned on page 161 of "Genealogy, Local History, Early maps of MD, DE, So. PA and Washington DC" published 1988 by Family Line Publications.  The author was Martha Reamy.

MARYLAND CORBIN FAMILY (Furnished by Mrs. Effie S. Honson, of Ventura, California, to Mrs. J. W. Marr, Lexington, Ky.) NICHOLAS CORBIN — Came to Baltimore Co., Md. in 1671. (Authority, "Early Maryland Settlers List." "Annapolis land office records. Vol. XVI., page 533."  Alice, wife of Nicholas Corbin, 2nd., mar. John Barrot.  (Annapolis Md. Inventories and Accounts, XX, page 47).  Children of Nicholas and Alice Corbin, 1, Elizabeth (Mr. Roberts); 2. Mary (mar. Gostwick); 3, Edward (mar. Jane Wilkinson, a daughter of Wm Wilkinson, 1718)...

Nicholas made the crossing with his first wife, Elizabeth, and daughters Elizabeth and Mary, so Alice was not their mother.  Alice does appear to have been Edward's mother.
