Ethnicities/Ancestry of Batdad and Batsiblings:
Canon: Bruce Wayne: Ambiguous European/Jewish (Ashkenazi)
His father's ethnicity is very vague, but it assumed to be European or Anglo-Saxon. I put ambiguous for him as we truly don't know. His mother is Jewish. (See below)
Canon: Dick Grayson: Ambiguous/Romani
John Grayson is mixed and pretty inconsistent. John's paternal grandparents were Caucasian, however, his maternal side is unknown/ambiguous. In past comics, John was portrayed as Romani. The only retcon was his paternal grandfather being William Cobb (Dick's great-grandfather). Therefore, John Grayson can be considered Ambiguous/Romani assuming his maternal side is Roma. Dick's dad also canonically speaks Romani. Mary Grayson is French Romani (Romani born and raised in France). Dick was raised with the culture and language. Please note, the way the Romani culture is portrayed in the comics is very stereotypical. When writing about the Romani culture in fanfics, I highly encourage you to research the culture (actual case studies, interviews with Romani people and well-respected sources, wiki is not enough)
Jason Todd: (canon) Ambiguous European; (popular fandom headcanon) Hispanic
As of right now, Jason is considered canonically ambiguous European. His grandmother, Ma Gun, is from Australia which is basically all we know.
Many fans love to headcanon Jason as Hispanic/Latino. Not sure why, but please be aware of any potential stereotypes. Personally, I love Hispanic/Latino Jason. However, sometimes, I get worried that fans headcanon Jason as Hispanic due to his background (homeless, street kid, drug addict mother, abusive/criminal father), making the headcanon kind of racist. (Soy Boricua pa' que tu lo sepas, don't come for me) Headcanons are fine as long as there is no racial stereotype behind it.
Tim Drake: (canon) Ambigous/Caucasian; (popular fandom headcanon) Asian
Like Jason, considered canonically white. AND like Jason again, be careful with stereotypes. I'm not sure where the Asian headcanon came from, but again, I worry it's because Tim is a genius, a tech geek, and well-off, which are racial stereotypes of Asian-Americans.
Cassandra Cain: (canon) Chinese/ambiguous European
Her mother, Lady Shiva, is of Chinese ancestry. Her father, David Cain, is considered canonically white, ancestry some where in Europe.
Damian Wayne: (canon) Ambigous European/Jewish/Chinese/Middle Eastern/Arabic; (popular fandom headcanon) Jewish/Arabic
Damian is canonically very mixed. His father is Bruce, making him Jewish and European. His mother, Talia, is Chinese/Middle Eastern. This is where it gets a bit tricky. Ra's al Ghul's backstory has been inconsistent over the years. He was born and raised in an eastern North African nomadic tribe, but also had some Byzatine Roman ancestry at one point. However, his father, Sensei, is Chinese. His mother, Mother Soul/Rúh al Ghul, is assumed to be Middle Eastern/Arabic. Talia's mother, Melisande, is assumed to be Arabic/Chinese.
Evidence: Please refer to this Tumblr post for the breakdown. It was too much for me lol

As for the fandom headcanon, I'm not sure how many fans were actually aware of how ethnically mixed Damian is.
Canonically, the League of Assasins have their own dialect, but it has Arabic influence. In the Gotham Knights game (2022), it was close to Berber (Tamazight), North African languages spoken by indigenous groups.
Duke Thomas: African-American/Unknown
His mother, Elaine Thomas, is African-American. His biological father's , Gnomon, ethnicity is completely unknown. He is said to be over 1,000 years old and is immortal.
Please feel free to add or make corrections! I did this at 11:55 PM after an anxiety attack, so it could be off 😅
