1. Did you read ACOM's description of the data sets?
"Millions of individual records were created (while gathering genealogical data for use in the study of human genetics and disease) from birth, marriage and death records; obituaries; probate records; books of remembrance; family histories; genealogies; family group sheets; pedigree charts; and other sources."
2. Did you read ACOM's caveat for the data sets?
"When you find the name of an ancestor listed, confirm the facts in original sources, such as birth, marriage, and death records, church records, census enumerations, and probate records for the place where the even took place."
3. Do you realize that all of the entries are undocumented as disclosed by ACOM?
". . . despite the absence of cited documentation, the electronic rights to the data were purchased, rather than see it destroyed."
So, in essence you have been accepting hints for people whose source is suspect and whose documentation is totally lacking. No matter how much time you spent, it was probably too much. And you will spend even more time unwinding the problems you may have created in your tree.
