Maywic Management

Mayo T. Stuntz Jr. and Wickham M. McMillan are identified in public records as the principals of Maywic Management. Both are descendants of the Grace family that founded W. R. Grace & Co. The firm operates with a small, insular team where investment decisions are made directly by the principals, consistent with the governance model of most classic single-family offices.

The wealth managed by Maywic Management originates from W. R. Grace & Co., founded in 1854 by William Russell Grace. The company grew into a global industrial conglomerate with dominant positions in shipping, chemicals, and mining across South America. The family's fortune was built over multiple generations as the firm became a major force in 20th-century Latin American commerce.

No. Public records and regulatory filings consistently show Maywic Management as a single-family office managing proprietary capital. There is no evidence of the firm marketing funds, accepting institutional limited partners, or operating as a multi-family office. It adheres to the classic single-family-office model of serving one family's balance sheet.

Maywic concentrates on publicly traded equities and commercial real estate. The equity portfolio, visible through periodic 13F filings, emphasizes large-cap companies in industrial, financial, and consumer sectors. The real estate holdings are privately held, typically income-producing commercial properties in major US markets, acquired for long-term stewardship rather than rapid capital appreciation.

Maywic Management is the investment office for descendants of the Grace family who founded and controlled W. R. Grace & Co. The chemical and materials company, which went public and later underwent restructuring, was the engine of the family's wealth. The family office now operates independently, investing the family's liquid assets rather than managing an operating business.
