Jarrett D. Terrill has written an article that is both thought-provoking and probably controversial as well. It describes family genealogy from the viewpoint of someone who is gay. He writes, "Genealogy can be very exciting but it can also drudge up some insecurity with people if their particular family structure is one of a more 'modern' nature."
He also writes, "Bloodline relationships and marriage certificates will always be the gold standards in genealogical research but the fabric of our history is so much more than that. Adopted and foster children certainly want to know as much about their adoptive family as they do about their ancestors. Often times, our friends and non-relatives are just as important to who we really are in society regardless of scholarly tradition or bleak and flavorless medical records."
