Heartious congtatulations to u n ur family!
Don't intend on spoiling the mood but just want to point out one thing. U mentioned how Allah has showered blessings on ur family...its true that worldly wealth is a blessing but it is not the sole criteria of success. And for some, this wealth comes as a test from the Almighty so spend it wisely, thanking Allah at each passing moment. And never forget the times when things were not so bright as far as worldly wealth is concerned. For it is indeed Allah Who gives of His provision to whom He wills.
