These 3 second level characters are halflings, Alberto, Cedrick and Daisy. Click the link to download the PDF file. These characters are almost ready to go. In generating ability scores, I made sure the range was acceptable in both D&D and AD&D. To convert these characters to straight AD&D, simply add or subtract the racial modifiers and class abilities.
In my campaign, halflings are invaders and refugees. These characters have far more than a typical adventurer would have owing to the fact that they are homeless.
If there is a call for it in the comments, I will make DOCX and Google Doc file available as I have the PDFs. The reason I have not done this from the get go is that I created every character of a class in one document and print each page as a PDF.
