I show Gardner Brewer being born 1808 in VT and Charlotte Barr born 1809 in VT. I don't know where Gardner and Charlotte are buried but there are a couple people in the Richland Center, WI area that is looking besides me.
I would love to find out how you are related to Gardner and would be happy to share what I have. I live in Rochester, MN and have been doing genealogy for about a year and find it fascinating. I hope to hear from you soon. I will also send this message directly to you.
One record I have from a relative in MA shows the following children for Gardner and Charlotte:
Sebastian, Mary, Hannah, Conrad, John, Jeremiah, Peter E., Allen S., Albert, Charlotte and Ida. There is a Sebastian Brewer (born in VT) buried in a cemetery in Baraboo, WI.
