Thanks, but it's not clear-- "More than $100,000 from a nonresident alien individual or a foreign estate (including foreign persons related to that nonresident alien individual or foreign estate)" Looks like it's aggregated if it's relatives- brother and sister or brother and wife.
Gifts that are received from related individuals must be aggregated to determine if you need to report. For example, if one nonresident gave you $40,000 and another related nonresident gave you $70,000, because the total is above $100,000, you will need to report the gift." https://www.lindsayandbrownell.com/a-gift-from-your-foreign-relative-could-cost-you/
