What is President Abrahan Lincoln heritage or nationality.  I.e where
in europe does his family come from?

Hello.

Abraham Lincoln's great-great-great-great-grandfather, Samuel Lincoln,
came from England.  Thus, his heritage was English.

From the National Archives:

"ABRAHAM LINCOLN
16th U.S. President 1861-1865
LIFETIME: 1809-1865, of English ancestry "

Here's an interesting article about the area of England from which
Abraham Lincoln's ancestors came:

I hope this helps.

A person has 64 great-great-great-great-grandparents.  So this
accounts for 1/64th of his heritage.  However, it does account for the
lineage of his surname.

Thank you for your comment, ansel001.  This was a $3 question, so an
exhaustive review of Lincoln's lineage was likely not expected.  A
review of one of the sites that I mentioned above indicates that
essentially all of Lincoln's other ancestors were English and/or
British.

If you have any information related to significant non-British
heritage in Lincoln's family tree, it would be a welcome addition to
this thread.

According to "The Complete Book of U.S. Presidents" by William A. DeGregorio:
"Lincoln was of English ancestry. His great-grandfather Samuel Lincoln
emigrated from Norfolk, England, arriving at Higham, Massachussetts,
about 1637. Subsequent generations migrated to New Jersey,
Pennsylvania, and Virginia. His paternal grandfather and namesake,
Abraham Lincoln, served as a captain in the Virginia militia during
the American Revolution. Hearing his friend Daniel Boone talk of cheap
land in Kentucky, he moved in 1782 to Jefferson County east of
Louisville. Four years later, while working his fields, he was shot
and killed by an Indian."
