AncestryDNA now provides some cM information |
I was quite disappointed when a 3rd cousin was predicted to be a 4th to 6th cousin a couple of weeks ago. I feel this is a bad call. According to Ancestry this person shares 50 cMs with me, which is in line with a 3rd cousin relationship. Glad I was able to see the shared cM's so I could dismiss the AncestryDNA prediction (sounds like someone at ISOGG on Facebook has a match sharing 6 cM's on 2 segments???). A second cousin's results came in a week ago and his relationship prediction was accurate. Looking at other matches I see that on average Ancestry is 7 cM's different than Family Tree DNA and GEDmatch. They can occasionally be as many as 20 cM's off. I think AncestryDNA should dump the Timber filter and use a more accurate filter. Sounds like more accurate filters process more slowly and are more costly? I would still like to see a chromosome browser. I'll lift my grade for AncestryDNA to a B. I would give it an A if they would provide a chromosome browser.
If you'd like to read more about the changes at 23andMe you can read this more in depth explanation at Kitty Cooper's Blog. I noticed I have double the number of matches (about 1800) I had before, but most are anonymous. Also some of the physical characteristics reports were far off. My mother was predicted to have dark eyes. Her eyes were light hazel. My eyes are dark which is correct.
Trip to Nicaragua:
I plan on leaving for a genealogy research trip to Granada, Nicaragua on December 7 (if all goes according to plan).
I have done some preliminary research. I've exchanged emails with an archive employee. He said that a staff member has found some information about my family. I have also learned about what is available at the archives from a distant cousin Alan (who is a DNA match). He has made a number of research trips to Nicaragua. He provided me with an index to the archive holdings.
My primary research location will be "Archivo de la Prefectura de la Municipalidad de Granada, Macario Álvarez", which contains 1,653 bundles of documents. This archive contains important genealogy sources such as Censuses and Military records. Another good source for Nicaragua was explained to me by my distant cousin Alan i.e. "recursos de habilitación are one of the more obviously genealogical series, they are coming of age documents usually the offspring of well to do families, in which they state that they are of legal age to enter into the administration of their patrimony and are x years of age, and their parents are x & x. I have not used this collection very much but it is specially useful for Granada families."
I hope to find more about our cousin Francisco Alvarado Granizo, and more about my Great-Grandparents Nicasio Del Castillo and Elena Garcia. According to my Aunt Grace, the informant on my Grandmother Graciela's death certificate, her parents were Nicasio Del Castillo and Elena Garcia. My Mother knew her grandmother was Elena. She didn't know her maiden name, or her grandfather's name. I believe Aunt Grace was a good informant because she worked as a secretary for many years and was very organized when it came to keeping documents. My mother said her grandfather was a lawyer, which seems to suggest a relationship with Nicasio Del Castillo who left 28 years worth of legal books at the Granada Archives, which dated from 1857 to 1884. This Nicasio would seem to be too old to be my grandmother's father? Since the legal profession tended to be a family profession the elder Nicasio may have been my grandmother's grandfather? My grandmother was born in 1893.
The death certificate for my grandmother Graciela Del Castillo is the only document I have naming my great-grandparents.


It will be interesting to see where my Grandparents and mother lived. My Grandfather Charles Forgey was born in Indiana. Ran away from home at age 17, joined the Marines in 1916 and was sent to Nicaragua. He married my Nicaragua native grandmother Graciela Del Castillo in 1919. My mother Edna was born in 1921. The family left Nicaragua in 1925 and settled in California. I'm a little apprehensive about traveling to a "Third World" country. I've gotten hepatitis and Typhoid vaccinations in preparation. Hoping all goes smoothly?

Hi Annette,
Very interesting post. Even more interesting when I saw mention of Granada! A relative of mine (by marriage) disappeared in Nicaragua when William Walker recruited him to join his brigade. Edwin (Edward) Marmaduke Tilden was a newly minted medical doctor with a new practice in Philadelphia, recently married, and seems to have left before his first (and only known child) was born. A descendant was Big Bill Tilden, a well-known tennis star. His recently-widowed older brother, also a doctor, married my relative in Chico, California about the same time Edwin decamped from Philadelphia. I'm in touch with a couple of Tilden descendants (one of them my known 5th cousin, accurately pegged by Ancestry as a 4-6th cousin), and they would be eager to hear if you found any evidence of Edwin M Tilden's time in Nicaragua ( if indeed he ever arrived).
I spent a couple of weeks in Nicaragua during the Iran-Contra fiasco and found the people lovely and welcoming, although unhappy that my country was financing a war in theirs. I knew about the William Walker precedent at the time, but not my family's connection to it. As you may know, he recruited heavily in Cslifornia.

Thank you Julie! A researcher in the archives in Nicaragua said the archives are badly managed Some records for the filibuster period may survive? No one has completely indexed the 1600 bundles. Wonder if Edwin left children in Nicaragua? He may have been killed or just started a new life there? You never know.
My descendant and my mother-in-law have both been tested with AncestryDNA. We were scratching our heads when we saw that grandma was a predicted first cousin match. Granted, they share slightly less than the predicted grandparent amount, but still.
Have a FABULOUS trip to Nicaragua! We'll miss you at the SL Christmas Party, but know you will be doing what you love. Hope you find everything you're looking for! :-)
Hi Annette,
The usefulness of the "Countries Of Origin" tool at 23andMe depends on your perspective - Don't forget some of us testers are from the "Old World" !
Re Timber and AncestryDNA: I have two cousins who both tested at Ancestry and both are on GEDmatch. They are 5th cousins to each other and share 21cM, but they are not shown as a match to each other on Ancestry! Timber's algorithm tossed the match as IBS. Not good.
Travel safely and have a good trip! I'm eager to hear all about it. When do expect to be home?
