Hi Stephanie,
Welcome to Rootschat!

There were many reasons names got 'munted'. Illiteracy was one, especially combined with foreign accents being difficult to 'hear', and resulting best-guess phonetic renderings by American record keepers/clerks/Priests etc. Many immigrants also chose to 'anglicise' their names themselves, sometimes trying a few versions before they settled on, or were steered towards, one.
Here are some thoughts that might help get things rolling for you:
Post a snip or two of the 1897 document, showing the name as it's written and / or signed and enough if the same handwriting in other parts of the documents to be able to compare. You can't post the whole document, but can post parts of it. Also make sure snips you post are of a high res. This is the board where that generally happens, post a new topic :
http://www.rootschat.com/forum/index.php?board=425.0Explain there that the Document you have is from the US, too; even though it's all English, the 'flavour' of a document can help when working out handwriting .
Post the url link to that new topic, onto this topic and then we can follow (or have a go).
Explain to us here on this topic, more about your research and current obstacles:
What is the name, as it is used today by descendants?
What was the name in each Census 1900 to 1930? Right or wrong, are the Census' clear? Have you got him in all possible census he could be in?
Are you trying to now move back and finding the name variations a stumbling block? Perhaps you could type up (not copy-paste!) and post all the Census you have. Post all the details as they will answer a lot of the questions we as 'helpers' would initially want to know, such as:
Was he able to read and write?
Was he born outside of the US, if so where and when did he arrive in the US?
If born in the US, where? and where were his parents born?
Cheers
