I also agree Tacey is a hard name to research. My grandfather had 2 daughters, so he doesn't have anyone to carry the Tacey name on.
Do you know what nationality your family is from? The only reason I ask is that sometimes I wonder if Tacey was short for something else or if it was spelled or pronouced differently in some other country.
I have always thought Tacey was Irish.
I have to send away for James, Harry Edward Green Tacey's birth certificates. As far as I know my Grandfather,his brother sister were born in Westerport,MD. His father Harry was born in Winchester, Va or Harpers Ferry, Va.
The Jefferson Tacey that my mom has an old picture of is listed in the mormon website
www.familysearch.org. There are a few Tacey's listed there, you might want to take a look at.
I believe there was an Green Tacey Edward Tacey in there also.
Jefferson's parents are listed as George Jane Tacey from England. Also, I think he had a brother named George William, because they have the same parents.
Also in FamilyTree maker shows Jefferson Tacey on the 1860, 1870 Va. census'.
I also thought I had seen that George William lived in Va had a son named George also.
If you find any websites or info on Tacey please let me know. Thanks.
