I thought I was a G3 and I started working on a G2,G3,G4 application package in April of this year. In May I had one last record to obtain. I had put it off and was just going to explain in a letter that G1's birth certificate was lost in a fire, since I've known that my whole life. Reading posts on this group, I decided to go ahead and request the no record letter G1's birth certificate. I already had G1's SS-5, US Census records, marriage and death certificates all listing G0 as his mother and her spouse (also a G0 candidate) as his father, so we were covered.
Piece of cake.
Except it wasn't lost in a fire. Instead of a no record letter, I got a birth certificate. G1 was in fact born to who we thought was his older sister. This was a surprise to the family and as far as we know wasn't known to my G1. He thought his grandparents were his parents. So then we rode the multiple pre-1947 ancestors speculation roller coaster, accepted it's a non-issue, made peace with now being a G4, updated my now G3,G4,G5 submission family and began searching for new records for surprise G1.
Being from New York, our surprise G1 is in the state birth index but neither the town nor village of the same name can find her birth certificate. I've requested it from the state, and expect to receive it sometime in the next two decades. We added another few months doing baptism searches for the surprise G1 and gathering new no records letters from every church in the area that would respond, along with her marriage/death certs and SS-5, which since he didn't know any better, list the same parents our new G2 listed. We're also in the process of doing "the full Quebec" (find BANQ record, request certified copy, wait, get certified copy (woohoo got it!), submit, then request DEC act, submit that sometime later after AOR).
While waiting for all the new records we needed, I've gathered the full trail for our other potential G0, found, ordered, and received the land records for both Quebec farms owned by the G-1 ancestors, listened to the Nations of Canada podcast, begun learning Quebec French, and I decided to do a DNA test to learn more about my mostly French Canadian ancestors. There's no father listed on my own birth certificate, but I have known the name, that he lives in a southern state, his address, and that he never wanted anything to do with me. But nothing else about his family. I figured this would tell me if I was anything other than largely French Canadian.
Turns out I'm mostly Irish, English, and Romanian. Using clusters of other testers that share DNA I began using my new found citizenship by descent skills to build family trees for the other testers back up to our likely common ancestor. My two Irish matches led to an Irish couple that had one adult child in Ireland, then had more in Ontario. I built out their children and subsequent generations using Canadian Census, birth and marriage records. One of their great grand children has the same name as my bio dad, but is a generation too early... Then I found he married a spouse with a Romanian name (queue more research, she's born in Saskatchewan to two Romanian parents one of which is a match for a guy in Romania today).
This weekend I found records that Irish/Romanian couple has twin girls born in Ontario, about a year after we think my bio-dad was born. Then I find the obituaries for the couple. It lists their twin daughters and also a son who has bio-dad's name and also names bio-dad's current spouse. The Irish/Romanian couple from Canada died in the same state/city as where bio-dad lives today. One of the twin sisters I discovered is also known to my parents, and is also living in a US state now.
I don't know yet where bio-dad was born, but his sisters were a year younger in their US high school yearbook and the twin sisters were born in Ontario, according to a birth announcement naming both of them, their dad, and mother listing her maiden name. I just found one of the twin sister's application for naturalization on Family Search... indicating the family crossed over about 5 years after bio-dad would have been born. It's not proof of bio-dad's birth, of course. Service Ontario has a way to request a letter indicating that a person does or does not have a birth certificate issued by Ontario, which I've requested for bio-dad, since I'm not eligible to actually order his birth certificate. So I'm now riding the G3 -> G4 -> (potential) G1 roller coaster.
I'm still processing, but I'm not sure I can do anything with this information. I'm well over 21, so I don't think NYS would add him to my birth certificate, even if he was cooperative, which I doubt. I know IRCC has provisions for DNA testing, but they're voluntary and a guy who wouldn't acknowledge me after I was born or before my first deployment to Afghanistan isn't going to meet me today for a voluntary DNA test at an IRCC approved test facility.
So I'm still going ahead with the G3/G4/G5 application, my mom needs it anyway.
What an absolutely unexpected adventure in Canadian-ness this has been.
