Don't neglect to copy or scan those "marks," "wiggles, and "annotations" that appear to be doodles on a document or a church record. They could be an abbreviation or annotation that has significance. Try and get the entire page from the book or other records that have the same or similar markings.
Then see if you can find someone to help you interpret those markings. They may be scribbles or they may have some meaning. Doodles aren't always doodles.
