I do not have any Brainerd Thesings in my databases.I have known about you Brainerd folks for a number of years but I haven't found anyone willing to spend enough time to give me details on the individuals or tell me where they fit into the databases.If you are of a mind to do so, please be my guest.I promise to update the databases and send you a printed copy.
I don't have Leanders in the databases either.It runs in my mind that there is a Thesing/Leander connection that I ran into about 10 or 12 years ago.These Leanders left Minnesota and settled on the west coast area, Seattle I think.
I have charts of the various Thesing family groups published on a Family Tree Maker web page.They are a bit out of date but not much.Why don't you take a look at them,first Heinrich from Herbrum and then John Henry from Wullen.See if you can locate the place where your Brainerd group connects and let me know.
Click on the URL below and it should take you directly to the web page.If that doesn't work, cut and paste the URL into your browser's address line and go to it.Once you get the web page spin down to the bottom of the page for the Heinrich and John Henry charts.These are two unrelated (as yet) family groups.
Thanks for your interest in our family and happy hunting.
