Puerto Rico: My Ancestors and Their Descendants

To make things a little simpler for myself, I created a chart that would easily calculate the ages of those found in the 1910 and 1920 census sheets. The way one should read this is: for the year 1910 read column(s) from left to right and for the year 1920 read column(s)from right to left. Hope it is helpful...

If Age in 1910 Was	Year of Birth Was	If Age in 1920 Was	If Age in 1910 Was	Year of Birth Was	If Age in 1920 Was
