For a girl, she can be named Yin Zining. "Ning" has the same pronunciation as Lin, which blends her parents' surnames into it and reflects the beautiful love between her parents.
For a boy, you can name him Yin Linhua or Yin Hanlin
Both names contain the surnames of the parents, and both names imply that the baby will be broad-minded and open to all rivers
I tried my best. I originally wanted to think of a few more names for the girl to incorporate the two surnames, but your husband’s surname is more difficult to name
