Linda,

With the number of Harrison's out there, you definitely need a little more information. The same names were used in many different Harrison families over about a hundred years, so you need to place your Harrisons somewhere in time.

Secondly, Benjamin Harrison is also a common name. The Benjamin Harrison who was the signer of the Declaration of Independence was number Five!! And many of his siblings and cousins also had children that they named "Benjamin".

I looked in the 2 primary places to find Harrisons. First there are the R. Bolling Batte Paper at the Library of Virginia. Names are alphabetical. I looked for a Mary Harrison married to someone named Wright and found nothing. There were several Wrights, but none with a first name starting with B (the cards went from A to C).

Then, I went to the Harrison Genealogy Repository. There were more names there, but without more information, it was impossible to determine if any of them was the right Mary. I counted about 230 Mary Harrisons, 11 were Mary Jane's but no Mary Jan or Jean. There were a few Wrights, but no Burs.
(You can google them and find the website easier than I can type in the UrL.)

I have an unofficial family tree for the Harrisons starting with Benjamin IV that I can look at in a day or two...I've got to dig out the file...but there's still no guarantee that I can find Mary.

I would suggest that you try to get some dates for this couple and find out where they lived so that you can look for census records. You mentioned Ohio. Most of the Harrisons related to Benjamin V lived in Virginia, but his youngest son, William Henry Harrison, moved to Ohio sometime before he ran for president. You need to know their approximate locatiion to look in census records.

I will look in a couple of other places. You made this posting of the Free Persons of Color forum. How do these two people connect to a Free Person of Color?

Hope this information is helpful. I will do a little more looking and get back to you.
