Sorry it took me so long to answer your question about the year of birth
for Calvin Latta, son of Isaac.
Robert Latta's book has Calvin as born Oct.22,1848. It also has his
brother, Albert, born Nov.1,1848. This couldn't be!
My records show this:
Clifford Latta: b. 1836
Albert Latta: b. 1838
Calvin Latta: b. 1840
Luther Latta: b. 1841
George Latta: b. 1845
These are all sons of Isaac Latta & Nancy Welch.
There's no way of knowing if these dates are right, but they do seem to
be pretty close in age, don't you think? Don't know where the 1850 date
