Ah. Sorry you’re having trouble getting to that page.

If you have a place somewhere on the Mueller family tree — as direct descendant, as spouse, or even as close friend or kindred spirit — then you should be able to move around the site freely and read whatever you like. You’ll need a username and password, but those are easily and quickly available. Here's how:

  1. Send email to that includes the following:
    • Your full name.
    • Your date of birth.
    • A brief description of your spot on the Mueller family tree — how you plug in and where.
  2. You will receive a username and password, usually within 24 hours. When you have them, go to and enter them in the spaces provided. As long as you allow your browser to set a cookie, the web will know you have a place on the Mueller family tree and you will not need to log in again. is built around a graphical representation of the family tree, beginning with Georg and Gertrude Mueller in Napoleanic times. Lots of other families plug in as direct descendants — Kniefs, Oltroges, Schumms, Nickels, Marquardts, Gramses, Feiertags, Rehwinkels — a Who’s Who of old Lutheran Church–Missouri Synod names. (C.F.W. Walther himself even has a small walk-on part.) There are even more families who found a place on the Mueller family tree through marriage. All are welcome.

Security and Privacy Policy

Less than a year after their arrival in America, the Muellers were swindled out of almost everything they owned by a dishonest land agent who may have had an ordained Lutheran co-conspirator. One swindle like that is enough for any family.

As American life and commerce moved online, so did the digital counterparts of the land agent who bilked Fritz Mueller. tries to take reasonable precautions; it pays to be careful. Our first line of defense is not to include personal contact information or anything of material value online. We print names and relationships, but we do not print addresses, phone numbers, e-mail addresses or any contact information — and we will never give anyone’s information to a third party. There is, however, very little in these pages that cannot be gotten elsewhere with a few clicks of the mouse.

How much security is enough? You would probably want something a little more robust for your online banking, but’s precautions should be enough to keep hobby hackers and automated web crawlers at bay. Our Family Tree pages are password-protected and are open only to people who have a place somewhere on the Mueller family tree. Many of our text pages are open to the public, though they do not contain much that is of value beyond the Mueller family.

Our site security is in your hands. Please do not share your username and password. If you know other Mueller friends and relations who would like access to the site, we will happily provide a username and password to anyone on the Family Tree no matter how distant the branch. Please ask them to contact the Archivist as above.

Fixing Errors, Adjusting Content

The idea was to construct a dependable family history as a series of web pages, allowing users to click backward and forward through the generations, following different family lines. The data points for such a project quickly mounted into the tens of thousands — variant spellings, differing dates for births or deaths, Anglicized names, and the whole matter of German translation — but at least there is data for the family tree pages.

The text files are a bit more delicate, since subjective judgments inevitably creep in. If you encounter something with which you disagree or something you know is not quite right, please Contact the Archivist.
