Sonic's Family Tree

I made this on powerpoint, but transferred it to paint. Anyway, this is how I figured Sonic's family tree, in a way, at the least his ancestry.

Here's the down-low:

I figure that Sonic IV (our Sonic) represents our modern games

Sonic III (Sonic's father) would have represented an older version of Sonic that was in Sonic CD and the Movie, and set somewhere back in the mid-1970's

Sonic II (Grandpa) would have been Sonic in Sonic Underground, set somewhere in the 40's or later 30's, say sometime around WWII

Sonic I (Great-Grandpa) would have been Sonic in Sonic SatAM, but the alternate where Sally was killed before they could have children, but he married Queen Aleena in the next kingdom over. It is unsure how Aleena got control of Mobotropolis, but oh well... Anyway, Sonic I's day may have been back during the roaring 20's, about midway.
