I know it gets a bit confusing but you did it mostly right and I've fixed the format of your family so it reads like the other player's families. So your family looks like this:
Username: MThenardHouse/Estate: Northcote Manor
Career/Position:
Earl of Northcote
LN: Payne
DH: Lord
William Percival CharlesDW: Lady
Josephine Cecilia Anne née Hodges
DS: Lord
Fredrick Thomas Henry (Heir to Northcote)
---DW: Lady
Augusta Susan née ?
DD: Lady
Honoria Ruby Jane Payne
---DH: Captain
Percival George Cavendish (Navy Captain, Southerton Grange)
DD: Lady
Rosamund Kate Charlotte Payne
---DH: Dr.
Ebenezer Henry John "
Jack" Schuyler (Doctor, Randalls Park)
The only thing that you could posibly change would be to give Lady
Augusta Susan a maiden name. Other than that I've fixed all of your titles which were mostly correct so you're all ready for the next round! :)
